DESCRIPTION
       You can query/set/replace/unset options with this command. The name is actually the
       section and the key separated by a dot, and the value will be escaped.

       Multiple lines can be added to an option by using the --add option. If you want to update
       or unset an option which can occur on multiple lines, a POSIX regexp value_regex needs to
       be given. Only the existing values that match the regexp are updated or unset. If you want
       to handle the lines that do not match the regex, just prepend a single exclamation mark in
       front (see also the section called “EXAMPLES”).

       The type specifier can be either --int or --bool, to make git config ensure that the
       variable(s) are of the given type and convert the value to the canonical form (simple
       decimal number for int, a "true" or "false" string for bool), or --path, which does some
       path expansion (see --path below). If no type specifier is passed, no checks or
       transformations are performed on the value.

       When reading, the values are read from the system, global and repository local
       configuration files by default, and options --system, --global, --local and --file
       <filename> can be used to tell the command to read from only that location (see the
       section called “FILES”).

       When writing, the new value is written to the repository local configuration file by
       default, and options --system, --global, --file <filename> can be used to tell the command
       to write to that location (you can say --local but that is the default).

       This command will fail with non-zero status upon error. Some exit codes are:

        1. The config file is invalid (ret=3),

        2. can not write to the config file (ret=4),

        3. no section or name was provided (ret=2),

        4. the section or key is invalid (ret=1),

        5. you try to unset an option which does not exist (ret=5),

        6. you try to unset/set an option for which multiple lines match (ret=5), or

        7. you try to use an invalid regexp (ret=6).

       On success, the command returns the exit code 0.

OPTIONS
       --replace-all
           Default behavior is to replace at most one line. This replaces all lines matching the
           key (and optionally the value_regex).

       --add
           Adds a new line to the option without altering any existing values. This is the same
           as providing ^$ as the value_regex in --replace-all.

       --get
           Get the value for a given key (optionally filtered by a regex matching the value).
           Returns error code 1 if the key was not found and the last value if multiple key
           values were found.

       --get-all
           Like get, but does not fail if the number of values for the key is not exactly one.

       --get-regexp
           Like --get-all, but interprets the name as a regular expression and writes out the key
           names. Regular expression matching is currently case-sensitive and done against a
           canonicalized version of the key in which section and variable names are lowercased,
           but subsection names are not.

       --get-urlmatch name URL
           When given a two-part name section.key, the value for section.<url>.key whose <url>
           part matches the best to the given URL is returned (if no such key exists, the value
           for section.key is used as a fallback). When given just the section as name, do so for
           all the keys in the section and list them.

       --global
           For writing options: write to global ~/.gitconfig file rather than the repository
           .git/config, write to $XDG_CONFIG_HOME/git/config file if this file exists and the
           ~/.gitconfig file doesn’t.

           For reading options: read only from global ~/.gitconfig and from
           $XDG_CONFIG_HOME/git/config rather than from all available files.

           See also the section called “FILES”.

       --system
           For writing options: write to system-wide $(prefix)/etc/gitconfig rather than the
           repository .git/config.

           For reading options: read only from system-wide $(prefix)/etc/gitconfig rather than
           from all available files.

           See also the section called “FILES”.

       --local
           For writing options: write to the repository .git/config file. This is the default
           behavior.

           For reading options: read only from the repository .git/config rather than from all
           available files.

           See also the section called “FILES”.

       -f config-file, --file config-file
           Use the given config file instead of the one specified by GIT_CONFIG.

       --blob blob
           Similar to --file but use the given blob instead of a file. E.g. you can use
           master:.gitmodules to read values from the file .gitmodules in the master branch. See
           "SPECIFYING REVISIONS" section in gitrevisions(7) for a more complete list of ways to
           spell blob names.

       --remove-section
           Remove the given section from the configuration file.

       --rename-section
           Rename the given section to a new name.

       --unset
           Remove the line matching the key from config file.

       --unset-all
           Remove all lines matching the key from config file.

       -l, --list
           List all variables set in config file.

       --bool
           git config will ensure that the output is "true" or "false"

       --int
           git config will ensure that the output is a simple decimal number. An optional value
           suffix of k, m, or g in the config file will cause the value to be multiplied by 1024,
           1048576, or 1073741824 prior to output.

       --bool-or-int
           git config will ensure that the output matches the format of either --bool or --int,
           as described above.

       --path
           git-config will expand leading ~ to the value of $HOME, and ~user to the home
           directory for the specified user. This option has no effect when setting the value
           (but you can use git config bla ~/ from the command line to let your shell do the
           expansion).

       -z, --null
           For all options that output values and/or keys, always end values with the null
           character (instead of a newline). Use newline instead as a delimiter between key and
           value. This allows for secure parsing of the output without getting confused e.g. by
           values that contain line breaks.

       --get-colorbool name [stdout-is-tty]
           Find the color setting for name (e.g.  color.diff) and output "true" or "false".
           stdout-is-tty should be either "true" or "false", and is taken into account when
           configuration says "auto". If stdout-is-tty is missing, then checks the standard
           output of the command itself, and exits with status 0 if color is to be used, or exits
           with status 1 otherwise. When the color setting for name is undefined, the command
           uses color.ui as fallback.

       --get-color name [default]
           Find the color configured for name (e.g.  color.diff.new) and output it as the ANSI
           color escape sequence to the standard output. The optional default parameter is used
           instead, if there is no color configured for name.

       -e, --edit
           Opens an editor to modify the specified config file; either --system, --global, or
           repository (default).

       --[no-]includes
           Respect include.*  directives in config files when looking up values. Defaults to on.

FILES
       If not set explicitly with --file, there are four files where git config will search for
       configuration options:

       $(prefix)/etc/gitconfig
           System-wide configuration file.

       $XDG_CONFIG_HOME/git/config
           Second user-specific configuration file. If $XDG_CONFIG_HOME is not set or empty,
           $HOME/.config/git/config will be used. Any single-valued variable set in this file
           will be overwritten by whatever is in ~/.gitconfig. It is a good idea not to create
           this file if you sometimes use older versions of Git, as support for this file was
           added fairly recently.

       ~/.gitconfig
           User-specific configuration file. Also called "global" configuration file.

       $GIT_DIR/config
           Repository specific configuration file.

       If no further options are given, all reading options will read all of these files that are
       available. If the global or the system-wide configuration file are not available they will
       be ignored. If the repository configuration file is not available or readable, git config
       will exit with a non-zero error code. However, in neither case will an error message be
       issued.

       The files are read in the order given above, with last value found taking precedence over
       values read earlier. When multiple values are taken then all values of a key from all
       files will be used.

       All writing options will per default write to the repository specific configuration file.
       Note that this also affects options like --replace-all and --unset. git config will only
       ever change one file at a time.

       You can override these rules either by command-line options or by environment variables.
       The --global and the --system options will limit the file used to the global or
       system-wide file respectively. The GIT_CONFIG environment variable has a similar effect,
       but you can specify any filename you want.

ENVIRONMENT
       GIT_CONFIG
           Take the configuration from the given file instead of .git/config. Using the
           "--global" option forces this to ~/.gitconfig. Using the "--system" option forces this
           to $(prefix)/etc/gitconfig.

       GIT_CONFIG_NOSYSTEM
           Whether to skip reading settings from the system-wide $(prefix)/etc/gitconfig file.
           See git(1) for details.

       See also the section called “FILES”.

EXAMPLES
       Given a .git/config like this:

           #
           # This is the config file, and
           # a '#' or ';' character indicates
           # a comment
           #

           ; core variables
           [core]
                   ; Don't trust file modes
                   filemode = false

           ; Our diff algorithm
           [diff]
                   external = /usr/local/bin/diff-wrapper
                   renames = true

           ; Proxy settings
           [core]
                   gitproxy=proxy-command for kernel.org
                   gitproxy=default-proxy ; for all the rest

           ; HTTP
           [http]
                   sslVerify
           [http "https://weak.example.com"]
                   sslVerify = false
                   cookieFile = /tmp/cookie.txt

       you can set the filemode to true with

           % git config core.filemode true


       The hypothetical proxy command entries actually have a postfix to discern what URL they
       apply to. Here is how to change the entry for kernel.org to "ssh".

           % git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'


       This makes sure that only the key/value pair for kernel.org is replaced.

       To delete the entry for renames, do

           % git config --unset diff.renames


       If you want to delete an entry for a multivar (like core.gitproxy above), you have to
       provide a regex matching the value of exactly one line.

       To query the value for a given key, do

           % git config --get core.filemode


       or

           % git config core.filemode


       or, to query a multivar:

           % git config --get core.gitproxy "for kernel.org$"


       If you want to know all the values for a multivar, do:

           % git config --get-all core.gitproxy


       If you like to live dangerously, you can replace all core.gitproxy by a new one with

           % git config --replace-all core.gitproxy ssh


       However, if you really only want to replace the line for the default proxy, i.e. the one
       without a "for ..." postfix, do something like this:

           % git config core.gitproxy ssh '! for '


       To actually match only values with an exclamation mark, you have to

           % git config section.key value '[!]'


       To add a new proxy, without altering any of the existing ones, use

           % git config --add core.gitproxy '"proxy-command" for example.com'


       An example to use customized color from the configuration in your script:

           #!/bin/sh
           WS=$(git config --get-color color.diff.whitespace "blue reverse")
           RESET=$(git config --get-color "" "reset")
           echo "${WS}your whitespace color or blue reverse${RESET}"


       For URLs in https://weak.example.com, http.sslVerify is set to false, while it is set to
       true for all others:

           % git config --bool --get-urlmatch http.sslverify https://good.example.com
           true
           % git config --bool --get-urlmatch http.sslverify https://weak.example.com
           false
           % git config --get-urlmatch http https://weak.example.com
           http.cookiefile /tmp/cookie.txt
           http.sslverify false


CONFIGURATION FILE
       The Git configuration file contains a number of variables that affect the Git commands'
       behavior. The .git/config file in each repository is used to store the configuration for
       that repository, and $HOME/.gitconfig is used to store a per-user configuration as
       fallback values for the .git/config file. The file /etc/gitconfig can be used to store a
       system-wide default configuration.

       The configuration variables are used by both the Git plumbing and the porcelains. The
       variables are divided into sections, wherein the fully qualified variable name of the
       variable itself is the last dot-separated segment and the section name is everything
       before the last dot. The variable names are case-insensitive, allow only alphanumeric
       characters and -, and must start with an alphabetic character. Some variables may appear
       multiple times.

   Syntax
       The syntax is fairly flexible and permissive; whitespaces are mostly ignored. The # and ;
       characters begin comments to the end of line, blank lines are ignored.

       The file consists of sections and variables. A section begins with the name of the section
       in square brackets and continues until the next section begins. Section names are not case
       sensitive. Only alphanumeric characters, - and . are allowed in section names. Each
       variable must belong to some section, which means that there must be a section header
       before the first setting of a variable.

       Sections can be further divided into subsections. To begin a subsection put its name in
       double quotes, separated by space from the section name, in the section header, like in
       the example below:

                   [section "subsection"]


       Subsection names are case sensitive and can contain any characters except newline
       (doublequote " and backslash have to be escaped as \" and \\, respectively). Section
       headers cannot span multiple lines. Variables may belong directly to a section or to a
       given subsection. You can have [section] if you have [section "subsection"], but you don’t
       need to.

       There is also a deprecated [section.subsection] syntax. With this syntax, the subsection
       name is converted to lower-case and is also compared case sensitively. These subsection
       names follow the same restrictions as section names.

       All the other lines (and the remainder of the line after the section header) are
       recognized as setting variables, in the form name = value. If there is no equal sign on
       the line, the entire line is taken as name and the variable is recognized as boolean
       "true". The variable names are case-insensitive, allow only alphanumeric characters and -,
       and must start with an alphabetic character. There can be more than one value for a given
       variable; we say then that the variable is multivalued.

       Leading and trailing whitespace in a variable value is discarded. Internal whitespace
       within a variable value is retained verbatim.

       The values following the equals sign in variable assign are all either a string, an
       integer, or a boolean. Boolean values may be given as yes/no, 1/0, true/false or on/off.
       Case is not significant in boolean values, when converting value to the canonical form
       using --bool type specifier; git config will ensure that the output is "true" or "false".

       String values may be entirely or partially enclosed in double quotes. You need to enclose
       variable values in double quotes if you want to preserve leading or trailing whitespace,
       or if the variable value contains comment characters (i.e. it contains # or ;). Double
       quote " and backslash \ characters in variable values must be escaped: use \" for " and \\
       for \.

       The following escape sequences (beside \" and \\) are recognized: \n for newline character
       (NL), \t for horizontal tabulation (HT, TAB) and \b for backspace (BS). Other char escape
       sequences (including octal escape sequences) are invalid.

       Variable values ending in a \ are continued on the next line in the customary UNIX
       fashion.

       Some variables may require a special value format.

   Includes
       You can include one config file from another by setting the special include.path variable
       to the name of the file to be included. The included file is expanded immediately, as if
       its contents had been found at the location of the include directive. If the value of the
       include.path variable is a relative path, the path is considered to be relative to the
       configuration file in which the include directive was found. The value of include.path is
       subject to tilde expansion: ~/ is expanded to the value of $HOME, and ~user/ to the
       specified user’s home directory. See below for examples.

   Example
           # Core variables
           [core]
                   ; Don't trust file modes
                   filemode = false

           # Our diff algorithm
           [diff]
                   external = /usr/local/bin/diff-wrapper
                   renames = true

           [branch "devel"]
                   remote = origin
                   merge = refs/heads/devel

           # Proxy settings
           [core]
                   gitProxy="ssh" for "kernel.org"
                   gitProxy=default-proxy ; for the rest

           [include]
                   path = /path/to/foo.inc ; include by absolute path
                   path = foo ; expand "foo" relative to the current file
                   path = ~/foo ; expand "foo" in your $HOME directory

   Variables
       Note that this list is non-comprehensive and not necessarily complete. For
       command-specific variables, you will find a more detailed description in the appropriate
       manual page.

       Other git-related tools may and do use their own variables. When inventing new variables
       for use in your own tool, make sure their names do not conflict with those that are used
       by Git itself and other popular tools, and describe them in your documentation.

       advice.*
           These variables control various optional help messages designed to aid new users. All
           advice.*  variables default to true, and you can tell Git that you do not need help by
           setting these to false:

           pushUpdateRejected
               Set this variable to false if you want to disable pushNonFFCurrent,
               pushNonFFMatching, pushAlreadyExists, pushFetchFirst, and pushNeedsForce
               simultaneously.

           pushNonFFCurrent
               Advice shown when git-push(1) fails due to a non-fast-forward update to the
               current branch.

           pushNonFFMatching
               Advice shown when you ran git-push(1) and pushed matching refs explicitly (i.e.
               you used :, or specified a refspec that isn’t your current branch) and it resulted
               in a non-fast-forward error.

           pushAlreadyExists
               Shown when git-push(1) rejects an update that does not qualify for fast-forwarding
               (e.g., a tag.)

           pushFetchFirst
               Shown when git-push(1) rejects an update that tries to overwrite a remote ref that
               points at an object we do not have.

           pushNeedsForce
               Shown when git-push(1) rejects an update that tries to overwrite a remote ref that
               points at an object that is not a commit-ish, or make the remote ref point at an

               In case of failure in the output of git-rm(1), show directions on how to proceed
               from the current state.

       core.fileMode
           If false, the executable bit differences between the index and the working tree are
           ignored; useful on broken filesystems like FAT. See git-update-index(1).

           The default is true, except git-clone(1) or git-init(1) will probe and set
           core.fileMode false if appropriate when the repository is created.

       core.ignorecase
           If true, this option enables various workarounds to enable Git to work better on
           filesystems that are not case sensitive, like FAT. For example, if a directory listing
           finds "makefile" when Git expects "Makefile", Git will assume it is really the same
           file, and continue to remember it as "Makefile".

           The default is false, except git-clone(1) or git-init(1) will probe and set
           core.ignorecase true if appropriate when the repository is created.

       core.precomposeunicode
           This option is only used by Mac OS implementation of Git. When
           core.precomposeunicode=true, Git reverts the unicode decomposition of filenames done
           by Mac OS. This is useful when sharing a repository between Mac OS and Linux or
           Windows. (Git for Windows 1.7.10 or higher is needed, or Git under cygwin 1.7). When
           false, file names are handled fully transparent by Git, which is backward compatible
           with older versions of Git.

       core.protectHFS
           If set to true, do not allow checkout of paths that would be considered equivalent to
           .git on an HFS+ filesystem. Defaults to true on Mac OS, and false elsewhere.

       core.protectNTFS
           If set to true, do not allow checkout of paths that would cause problems with the NTFS
           filesystem, e.g. conflict with 8.3 "short" names. Defaults to true on Windows, and
           false elsewhere.

       core.trustctime
           If false, the ctime differences between the index and the working tree are ignored;
           useful when the inode change time is regularly modified by something outside Git (file
           system crawlers and some backup systems). See git-update-index(1). True by default.

       core.checkstat
           Determines which stat fields to match between the index and work tree. The user can
           set this to default or minimal. Default (or explicitly default), is to check all
           fields, including the sub-second part of mtime and ctime.

       core.quotepath
           The commands that output paths (e.g.  ls-files, diff), when not given the -z option,
           will quote "unusual" characters in the pathname by enclosing the pathname in a
           double-quote pair and with backslashes the same way strings in C source code are
           quoted. If this variable is set to false, the bytes higher than 0x80 are not quoted
           but output as verbatim. Note that double quote, backslash and control characters are
           always quoted without -z regardless of the setting of this variable.

       core.eol
           Sets the line ending type to use in the working directory for files that have the text
           property set. Alternatives are lf, crlf and native, which uses the platform’s native
           line ending. The default value is native. See gitattributes(5) for more information on
           end-of-line conversion.

       core.safecrlf
           If true, makes Git check if converting CRLF is reversible when end-of-line conversion
           is active. Git will verify if a command modifies a file in the work tree either
           directly or indirectly. For example, committing a file followed by checking out the
           same file should yield the original file in the work tree. If this is not the case for
           the current setting of core.autocrlf, Git will reject the file. The variable can be
           set to "warn", in which case Git will only warn about an irreversible conversion but
           continue the operation.

           CRLF conversion bears a slight chance of corrupting data. When it is enabled, Git will
           convert CRLF to LF during commit and LF to CRLF during checkout. A file that contains
           a mixture of LF and CRLF before the commit cannot be recreated by Git. For text files
           this is the right thing to do: it corrects line endings such that we have only LF line
           endings in the repository. But for binary files that are accidentally classified as
           text the conversion can corrupt data.

           If you recognize such corruption early you can easily fix it by setting the conversion
           type explicitly in .gitattributes. Right after committing you still have the original
           file in your work tree and this file is not yet corrupted. You can explicitly tell Git
           that this file is binary and Git will handle the file appropriately.

           Unfortunately, the desired effect of cleaning up text files with mixed line endings
           and the undesired effect of corrupting binary files cannot be distinguished. In both
           cases CRLFs are removed in an irreversible way. For text files this is the right thing
           to do because CRLFs are line endings, while for binary files converting CRLFs corrupts
           data.

           Note, this safety check does not mean that a checkout will generate a file identical
           to the original file for a different setting of core.eol and core.autocrlf, but only
           for the current one. For example, a text file with LF would be accepted with
           core.eol=lf and could later be checked out with core.eol=crlf, in which case the
           resulting file would contain CRLF, although the original file contained LF. However,
           in both work trees the line endings would be consistent, that is either all LF or all
           CRLF, but never mixed. A file with mixed line endings would be reported by the
           core.safecrlf mechanism.

       core.autocrlf
           Setting this variable to "true" is almost the same as setting the text attribute to
           "auto" on all files except that text files are not guaranteed to be normalized: files
           that contain CRLF in the repository will not be touched. Use this setting if you want
           to have CRLF line endings in your working directory even though the repository does
           not have normalized line endings. This variable can be set to input, in which case no
           output conversion is performed.

       core.symlinks
           If false, symbolic links are checked out as small plain files that contain the link
           text.  git-update-index(1) and git-add(1) will not change the recorded type to regular
           file. Useful on filesystems like FAT that do not support symbolic links.

           The default is true, except git-clone(1) or git-init(1) will probe and set
           core.symlinks false if appropriate when the repository is created.

       core.gitProxy
           A "proxy command" to execute (as command host port) instead of establishing direct
           connection to the remote server when using the Git protocol for fetching. If the
           variable value is in the "COMMAND for DOMAIN" format, the command is applied only on
           hostnames ending with the specified domain string. This variable may be set multiple
           times and is matched in the given order; the first match wins.

           Can be overridden by the GIT_PROXY_COMMAND environment variable (which always applies
           universally, without the special "for" handling).

           The special string none can be used as the proxy command to specify that no proxy be
           used for a given domain pattern. This is useful for excluding servers inside a
           firewall from proxy use, while defaulting to a common proxy for external domains.

       core.ignoreStat
           If true, commands which modify both the working tree and the index will mark the
           updated paths with the "assume unchanged" bit in the index. These marked files are
           then assumed to stay unchanged in the working tree, until you mark them otherwise
           manually - Git will not detect the file changes by lstat() calls. This is useful on
           systems where those are very slow, such as Microsoft Windows. See git-update-index(1).
           False by default.

       core.preferSymlinkRefs
           Instead of the default "symref" format for HEAD and other symbolic reference files,
           use symbolic links. This is sometimes needed to work with old scripts that expect HEAD
           to be a symbolic link.

       core.bare
           If true this repository is assumed to be bare and has no working directory associated
           with it. If this is the case a number of commands that require a working directory
           will be disabled, such as git-add(1) or git-merge(1).

           This setting is automatically guessed by git-clone(1) or git-init(1) when the
           repository was created. By default a repository that ends in "/.git" is assumed to be
           not bare (bare = false), while all other repositories are assumed to be bare (bare =
           true).

       core.worktree
           Set the path to the root of the working tree. This can be overridden by the
           GIT_WORK_TREE environment variable and the --work-tree command-line option. The value
           can be an absolute path or relative to the path to the .git directory, which is either
           specified by --git-dir or GIT_DIR, or automatically discovered. If --git-dir or
           GIT_DIR is specified but none of --work-tree, GIT_WORK_TREE and core.worktree is
           specified, the current working directory is regarded as the top level of your working
           tree.

           Note that this variable is honored even when set in a configuration file in a ".git"
           subdirectory of a directory and its value differs from the latter directory (e.g.
           "/path/to/.git/config" has core.worktree set to "/different/path"), which is most
           likely a misconfiguration. Running Git commands in the "/path/to" directory will still
           use "/different/path" as the root of the work tree and can cause confusion unless you
           know what you are doing (e.g. you are creating a read-only snapshot of the same index
           to a location different from the repository’s usual working tree).

       core.logAllRefUpdates
           Enable the reflog. Updates to a ref <ref> is logged to the file "$GIT_DIR/logs/<ref>",
           by appending the new and old SHA-1, the date/time and the reason of the update, but
           only when the file exists. If this configuration variable is set to true, missing
           "$GIT_DIR/logs/<ref>" file is automatically created for branch heads (i.e. under
           refs/heads/), remote refs (i.e. under refs/remotes/), note refs (i.e. under
           refs/notes/), and the symbolic ref HEAD.

           This information can be used to determine what commit was the tip of a branch "2 days
           ago".

           This value is true by default in a repository that has a working directory associated
           with it, and false by default in a bare repository.

       core.repositoryFormatVersion
           Internal variable identifying the repository format and layout version.

       core.sharedRepository
           When group (or true), the repository is made shareable between several users in a
           group (making sure all the files and objects are group-writable). When all (or world
           or everybody), the repository will be readable by all users, additionally to being
           group-shareable. When umask (or false), Git will use permissions reported by umask(2).
           When 0xxx, where 0xxx is an octal number, files in the repository will have this mode
           value.  0xxx will override user’s umask value (whereas the other options will only
           override requested parts of the user’s umask value). Examples: 0660 will make the repo
           read/write-able for the owner and group, but inaccessible to others (equivalent to
           group unless umask is e.g.  0022).  0640 is a repository that is group-readable but
           not group-writable. See git-init(1). False by default.

       core.warnAmbiguousRefs
           If true, Git will warn you if the ref name you passed it is ambiguous and might match
           multiple refs in the repository. True by default.

       core.compression
           An integer -1..9, indicating a default compression level. -1 is the zlib default. 0
           means no compression, and 1..9 are various speed/size tradeoffs, 9 being slowest. If
           set, this provides a default to other compression variables, such as
           core.loosecompression and pack.compression.

       core.loosecompression
           An integer -1..9, indicating the compression level for objects that are not in a pack
           file. -1 is the zlib default. 0 means no compression, and 1..9 are various speed/size
           tradeoffs, 9 being slowest. If not set, defaults to core.compression. If that is not
           set, defaults to 1 (best speed).

       core.packedGitWindowSize
           Number of bytes of a pack file to map into memory in a single mapping operation.
           Larger window sizes may allow your system to process a smaller number of large pack
           files more quickly. Smaller window sizes will negatively affect performance due to
           increased calls to the operating system’s memory manager, but may improve performance
           when accessing a large number of large pack files.

           Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32 MiB on 32 bit
           platforms and 1 GiB on 64 bit platforms. This should be reasonable for all
           users/operating systems. You probably do not need to adjust this value.

           Common unit suffixes of k, m, or g are supported.

       core.packedGitLimit
           Maximum number of bytes to map simultaneously into memory from pack files. If Git
           needs to access more than this many bytes at once to complete an operation it will
           unmap existing regions to reclaim virtual address space within the process.

           Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms. This should be
           reasonable for all users/operating systems, except on the largest projects. You
           probably do not need to adjust this value.

           Common unit suffixes of k, m, or g are supported.

       core.deltaBaseCacheLimit
           Maximum number of bytes to reserve for caching base objects that may be referenced by
           multiple deltified objects. By storing the entire decompressed base objects in a cache
           Git is able to avoid unpacking and decompressing frequently used base objects multiple
           times.

           Default is 96 MiB on all platforms. This should be reasonable for all users/operating
           systems, except on the largest projects. You probably do not need to adjust this
           value.

           Common unit suffixes of k, m, or g are supported.

       core.bigFileThreshold
           Files larger than this size are stored deflated, without attempting delta compression.
           Storing large files without delta compression avoids excessive memory usage, at the
           slight expense of increased disk usage.

           Default is 512 MiB on all platforms. This should be reasonable for most projects as
           source code and other text files can still be delta compressed, but larger binary
           media files won’t be.

           Common unit suffixes of k, m, or g are supported.

       core.excludesfile
           In addition to .gitignore (per-directory) and .git/info/exclude, Git looks into this
           file for patterns of files which are not meant to be tracked. "~/" is expanded to the
           value of $HOME and "~user/" to the specified user’s home directory. Its default value
           is $XDG_CONFIG_HOME/git/ignore. If $XDG_CONFIG_HOME is either not set or empty,
           $HOME/.config/git/ignore is used instead. See gitignore(5).

       core.askpass
           Some commands (e.g. svn and http interfaces) that interactively ask for a password can
           be told to use an external program given via the value of this variable. Can be
           overridden by the GIT_ASKPASS environment variable. If not set, fall back to the value
           of the SSH_ASKPASS environment variable or, failing that, a simple password prompt.
           The external program shall be given a suitable prompt as command-line argument and
           write the password on its STDOUT.

       core.attributesfile
           In addition to .gitattributes (per-directory) and .git/info/attributes, Git looks into
           this file for attributes (see gitattributes(5)). Path expansions are made the same way
           as for core.excludesfile. Its default value is $XDG_CONFIG_HOME/git/attributes. If
           $XDG_CONFIG_HOME is either not set or empty, $HOME/.config/git/attributes is used
           instead.

       core.editor
           Commands such as commit and tag that lets you edit messages by launching an editor
           uses the value of this variable when it is set, and the environment variable
           GIT_EDITOR is not set. See git-var(1).

       core.commentchar
           Commands such as commit and tag that lets you edit messages consider a line that
           begins with this character commented, and removes them after the editor returns
           (default #).

           If set to "auto", git-commit would select a character that is not the beginning
           character of any line in existing commit messages.

       sequence.editor
           Text editor used by git rebase -i for editing the rebase instruction file. The value
           is meant to be interpreted by the shell when it is used. It can be overridden by the
           GIT_SEQUENCE_EDITOR environment variable. When not configured the default commit
           message editor is used instead.

       core.pager
           Text viewer for use by Git commands (e.g., less). The value is meant to be interpreted
           by the shell. The order of preference is the $GIT_PAGER environment variable, then
           core.pager configuration, then $PAGER, and then the default chosen at compile time
           (usually less).

           When the LESS environment variable is unset, Git sets it to FRX (if LESS environment
           variable is set, Git does not change it at all). If you want to selectively override
           Git’s default setting for LESS, you can set core.pager to e.g.  less -S. This will be
           passed to the shell by Git, which will translate the final command to LESS=FRX less
           -S. The environment does not set the S option but the command line does, instructing
           less to truncate long lines. Similarly, setting core.pager to less -+F will deactivate
           the F option specified by the environment from the command-line, deactivating the
           "quit if one screen" behavior of less. One can specifically activate some flags for
           particular commands: for example, setting pager.blame to less -S enables line
           truncation only for git blame.

           Likewise, when the LV environment variable is unset, Git sets it to -c. You can
           override this setting by exporting LV with another value or setting core.pager to lv
           +c.

       core.whitespace
           A comma separated list of common whitespace problems to notice.  git diff will use
           color.diff.whitespace to highlight them, and git apply --whitespace=error will
           consider them as errors. You can prefix - to disable any of them (e.g.
           -trailing-space):

           ·   blank-at-eol treats trailing whitespaces at the end of the line as an error
               (enabled by default).

           ·   space-before-tab treats a space character that appears immediately before a tab
               character in the initial indent part of the line as an error (enabled by default).

           ·   indent-with-non-tab treats a line that is indented with space characters instead
               of the equivalent tabs as an error (not enabled by default).

           ·   tab-in-indent treats a tab character in the initial indent part of the line as an
               error (not enabled by default).

           ·   blank-at-eof treats blank lines added at the end of file as an error (enabled by
               default).

           ·   trailing-space is a short-hand to cover both blank-at-eol and blank-at-eof.

           ·   cr-at-eol treats a carriage-return at the end of line as part of the line
               terminator, i.e. with it, trailing-space does not trigger if the character before
               such a carriage-return is not a whitespace (not enabled by default).

           ·   tabwidth=<n> tells how many character positions a tab occupies; this is relevant
               for indent-with-non-tab and when Git fixes tab-in-indent errors. The default tab
               width is 8. Allowed values are 1 to 63.

       core.fsyncobjectfiles
           This boolean will enable fsync() when writing object files.

           This is a total waste of time and effort on a filesystem that orders data writes
           properly, but can be useful for filesystems that do not use journalling (traditional
           UNIX filesystems) or that only journal metadata and not file contents (OS X’s HFS+, or
           Linux ext3 with "data=writeback").

       core.preloadindex
           Enable parallel index preload for operations like git diff

           This can speed up operations like git diff and git status especially on filesystems
           like NFS that have weak caching semantics and thus relatively high IO latencies. When
           enabled, Git will do the index comparison to the filesystem data in parallel, allowing
           overlapping IO’s. Defaults to true.

       core.createObject
           You can set this to link, in which case a hardlink followed by a delete of the source
           are used to make sure that object creation will not overwrite existing objects.

           On some file system/operating system combinations, this is unreliable. Set this config
           setting to rename there; However, This will remove the check that makes sure that
           existing object files will not get overwritten.

       core.notesRef
           When showing commit messages, also show notes which are stored in the given ref. The
           ref must be fully qualified. If the given ref does not exist, it is not an error but
           means that no notes should be printed.

           This setting defaults to "refs/notes/commits", and it can be overridden by the
           GIT_NOTES_REF environment variable. See git-notes(1).

       core.sparseCheckout
           Enable "sparse checkout" feature. See section "Sparse checkout" in git-read-tree(1)
           for more information.

       core.abbrev
           Set the length object names are abbreviated to. If unspecified, many commands
           abbreviate to 7 hexdigits, which may not be enough for abbreviated object names to
           stay unique for sufficiently long time.

       add.ignore-errors, add.ignoreErrors
           Tells git add to continue adding files when some files cannot be added due to indexing
           errors. Equivalent to the --ignore-errors option of git-add(1). Older versions of Git
           accept only add.ignore-errors, which does not follow the usual naming convention for
           configuration variables. Newer versions of Git honor add.ignoreErrors as well.

       alias.*
           Command aliases for the git(1) command wrapper - e.g. after defining "alias.last =
           cat-file commit HEAD", the invocation "git last" is equivalent to "git cat-file commit
           HEAD". To avoid confusion and troubles with script usage, aliases that hide existing
           Git commands are ignored. Arguments are split by spaces, the usual shell quoting and
           escaping is supported. A quote pair or a backslash can be used to quote them.

           If the alias expansion is prefixed with an exclamation point, it will be treated as a
           shell command. For example, defining "alias.new = !gitk --all --not ORIG_HEAD", the
           invocation "git new" is equivalent to running the shell command "gitk --all --not
           ORIG_HEAD". Note that shell commands will be executed from the top-level directory of
           a repository, which may not necessarily be the current directory.  GIT_PREFIX is set
           as returned by running git rev-parse --show-prefix from the original current
           directory. See git-rev-parse(1).

       am.keepcr
           If true, git-am will call git-mailsplit for patches in mbox format with parameter
           --keep-cr. In this case git-mailsplit will not remove \r from lines ending with \r\n.
           Can be overridden by giving --no-keep-cr from the command line. See git-am(1), git-
           mailsplit(1).

       apply.ignorewhitespace
           When set to change, tells git apply to ignore changes in whitespace, in the same way
           as the --ignore-space-change option. When set to one of: no, none, never, false tells
           git apply to respect all whitespace differences. See git-apply(1).

       apply.whitespace
           Tells git apply how to handle whitespaces, in the same way as the --whitespace option.
           See git-apply(1).

       branch.autosetupmerge
           Tells git branch and git checkout to set up new branches so that git-pull(1) will
           appropriately merge from the starting point branch. Note that even if this option is
           not set, this behavior can be chosen per-branch using the --track and --no-track
           options. The valid settings are: false — no automatic setup is done; true — automatic
           setup is done when the starting point is a remote-tracking branch; always —  automatic
           setup is done when the starting point is either a local branch or remote-tracking
           branch. This option defaults to true.

       branch.autosetuprebase
           When a new branch is created with git branch or git checkout that tracks another
           branch, this variable tells Git to set up pull to rebase instead of merge (see
           "branch.<name>.rebase"). When never, rebase is never automatically set to true. When
           local, rebase is set to true for tracked branches of other local branches. When
           remote, rebase is set to true for tracked branches of remote-tracking branches. When
           always, rebase will be set to true for all tracking branches. See
           "branch.autosetupmerge" for details on how to set up a branch to track another branch.
           This option defaults to never.

       branch.<name>.remote
           When on branch <name>, it tells git fetch and git push which remote to fetch from/push
           to. The remote to push to may be overridden with remote.pushdefault (for all
           branches). The remote to push to, for the current branch, may be further overridden by
           branch.<name>.pushremote. If no remote is configured, or if you are not on any branch,
           it defaults to origin for fetching and remote.pushdefault for pushing. Additionally, .
           (a period) is the current local repository (a dot-repository), see
           branch.<name>.merge's final note below.

       branch.<name>.pushremote
           When on branch <name>, it overrides branch.<name>.remote for pushing. It also
           overrides remote.pushdefault for pushing from branch <name>. When you pull from one
           place (e.g. your upstream) and push to another place (e.g. your own publishing
           repository), you would want to set remote.pushdefault to specify the remote to push to
           for all branches, and use this option to override it for a specific branch.

       branch.<name>.merge
           Defines, together with branch.<name>.remote, the upstream branch for the given branch.
           It tells git fetch/git pull/git rebase which branch to merge and can also affect git
           push (see push.default). When in branch <name>, it tells git fetch the default refspec
           to be marked for merging in FETCH_HEAD. The value is handled like the remote part of a
           refspec, and must match a ref which is fetched from the remote given by
           "branch.<name>.remote". The merge information is used by git pull (which at first
           calls git fetch) to lookup the default branch for merging. Without this option, git
           pull defaults to merge the first refspec fetched. Specify multiple values to get an
           octopus merge. If you wish to setup git pull so that it merges into <name> from
           another branch in the local repository, you can point branch.<name>.merge to the
           desired branch, and use the relative path setting .  (a period) for
           branch.<name>.remote.

       branch.<name>.mergeoptions
           Sets default options for merging into branch <name>. The syntax and supported options
           are the same as those of git-merge(1), but option values containing whitespace
           characters are currently not supported.

       branch.<name>.rebase
           When true, rebase the branch <name> on top of the fetched branch, instead of merging
           the default branch from the default remote when "git pull" is run. See "pull.rebase"
           for doing this in a non branch-specific manner.

               When preserve, also pass `--preserve-merges` along to 'git rebase'
               so that locally committed merge commits will not be flattened
               by running 'git pull'.

           NOTE: this is a possibly dangerous operation; do not use it unless you understand the
           implications (see git-rebase(1) for details).

       branch.<name>.description
           Branch description, can be edited with git branch --edit-description. Branch
           description is automatically added in the format-patch cover letter or request-pull
           summary.

       browser.<tool>.cmd
           Specify the command to invoke the specified browser. The specified command is
           evaluated in shell with the URLs passed as arguments. (See git-web--browse(1).)

       browser.<tool>.path
           Override the path for the given tool that may be used to browse HTML help (see -w
           option in git-help(1)) or a working repository in gitweb (see git-instaweb(1)).

       clean.requireForce
           A boolean to make git-clean do nothing unless given -f, -i or -n. Defaults to true.

       color.branch
           A boolean to enable/disable color in the output of git-branch(1). May be set to
           always, false (or never) or auto (or true), in which case colors are used only when
           the output is to a terminal. Defaults to false.

       color.branch.<slot>
           Use customized color for branch coloration.  <slot> is one of current (the current
           branch), local (a local branch), remote (a remote-tracking branch in refs/remotes/),
           upstream (upstream tracking branch), plain (other refs).

           The value for these configuration variables is a list of colors (at most two) and
           attributes (at most one), separated by spaces. The colors accepted are normal, black,
           red, green, yellow, blue, magenta, cyan and white; the attributes are bold, dim, ul,
           blink and reverse. The first color given is the foreground; the second is the
           background. The position of the attribute, if any, doesn’t matter.

       color.diff
           Whether to use ANSI escape sequences to add color to patches. If this is set to
           always, git-diff(1), git-log(1), and git-show(1) will use color for all patches. If it
           is set to true or auto, those commands will only use color when output is to the
           terminal. Defaults to false.

           This does not affect git-format-patch(1) or the git-diff-* plumbing commands. Can be
           overridden on the command line with the --color[=<when>] option.

       color.diff.<slot>
           Use customized color for diff colorization.  <slot> specifies which part of the patch
           to use the specified color, and is one of plain (context text), meta
           (metainformation), frag (hunk header), func (function in hunk header), old (removed
           lines), new (added lines), commit (commit headers), or whitespace (highlighting
           whitespace errors). The values of these variables may be specified as in
           color.branch.<slot>.

       color.decorate.<slot>
           Use customized color for git log --decorate output.  <slot> is one of branch,
           remoteBranch, tag, stash or HEAD for local branches, remote-tracking branches, tags,
           stash and HEAD, respectively.

       color.grep
           When set to always, always highlight matches. When false (or never), never. When set
           to true or auto, use color only when the output is written to the terminal. Defaults
           to false.

       color.grep.<slot>
           Use customized color for grep colorization.  <slot> specifies which part of the line
           to use the specified color, and is one of

           context
               non-matching text in context lines (when using -A, -B, or -C)

           filename
               filename prefix (when not using -h)

           function
               function name lines (when using -p)

           linenumber
               line number prefix (when using -n)

           match
               matching text

           selected
               non-matching text in selected lines

           separator
               separators between fields on a line (:, -, and =) and between hunks (--)

           The values of these variables may be specified as in color.branch.<slot>.

       color.interactive
           When set to always, always use colors for interactive prompts and displays (such as
           those used by "git-add --interactive" and "git-clean --interactive"). When false (or
           never), never. When set to true or auto, use colors only when the output is to the
           terminal. Defaults to false.

       color.interactive.<slot>
           Use customized color for git add --interactive and git clean --interactive output.
           <slot> may be prompt, header, help or error, for four distinct types of normal output
           from interactive commands. The values of these variables may be specified as in
           color.branch.<slot>.

       color.pager
           A boolean to enable/disable colored output when the pager is in use (default is true).

       color.showbranch
           A boolean to enable/disable color in the output of git-show-branch(1). May be set to
           always, false (or never) or auto (or true), in which case colors are used only when
           the output is to a terminal. Defaults to false.

       color.status
           A boolean to enable/disable color in the output of git-status(1). May be set to
           always, false (or never) or auto (or true), in which case colors are used only when
           the output is to a terminal. Defaults to false.

       color.status.<slot>
           Use customized color for status colorization.  <slot> is one of header (the header
           text of the status message), added or updated (files which are added but not
           committed), changed (files which are changed but not added in the index), untracked
           (files which are not tracked by Git), branch (the current branch), or nobranch (the
           color the no branch warning is shown in, defaulting to red). The values of these
           variables may be specified as in color.branch.<slot>.

       color.ui
           This variable determines the default value for variables such as color.diff and
           color.grep that control the use of color per command family. Its scope will expand as
           more commands learn configuration to set a default for the --color option. Set it to
           false or never if you prefer Git commands not to use color unless enabled explicitly
           with some other configuration or the --color option. Set it to always if you want all
           output not intended for machine consumption to use color, to true or auto (this is the
           default since Git 1.8.4) if you want such output to use color when written to the
           terminal.

       column.ui
           Specify whether supported commands should output in columns. This variable consists of
           a list of tokens separated by spaces or commas:

           These options control when the feature should be enabled (defaults to never):

           always
               always show in columns

           never
               never show in columns

           auto
               show in columns if the output is to the terminal

           These options control layout (defaults to column). Setting any of these implies always
           if none of always, never, or auto are specified.

           column
               fill columns before rows

           row
               fill rows before columns

           plain
               show in one column

           Finally, these options can be combined with a layout option (defaults to nodense):

           dense
               make unequal size columns to utilize more space

           nodense
               make equal size columns

       column.branch
           Specify whether to output branch listing in git branch in columns. See column.ui for
           details.

       column.clean
           Specify the layout when list items in git clean -i, which always shows files and
           directories in columns. See column.ui for details.

       column.status
           Specify whether to output untracked files in git status in columns. See column.ui for
           details.

       column.tag
           Specify whether to output tag listing in git tag in columns. See column.ui for
           details.

       commit.cleanup
           This setting overrides the default of the --cleanup option in git commit. See git-
           commit(1) for details. Changing the default can be useful when you always want to keep
           lines that begin with comment character # in your log message, in which case you would
           do git config commit.cleanup whitespace (note that you will have to remove the help
           lines that begin with # in the commit log template yourself, if you do this).

       commit.gpgsign
           A boolean to specify whether all commits should be GPG signed. Use of this option when
           doing operations such as rebase can result in a large number of commits being signed.
           It may be convenient to use an agent to avoid typing your GPG passphrase several
           times.

       commit.status
           A boolean to enable/disable inclusion of status information in the commit message
           template when using an editor to prepare the commit message. Defaults to true.

       commit.template
           Specify a file to use as the template for new commit messages. "~/" is expanded to the
           value of $HOME and "~user/" to the specified user’s home directory.

       credential.helper
           Specify an external helper to be called when a username or password credential is
           needed; the helper may consult external storage to avoid prompting the user for the
           credentials. See gitcredentials(7) for details.

       credential.useHttpPath
           When acquiring credentials, consider the "path" component of an http or https URL to
           be important. Defaults to false. See gitcredentials(7) for more information.

       credential.username
           If no username is set for a network authentication, use this username by default. See
           credential.<context>.* below, and gitcredentials(7).

       credential.<url>.*
           Any of the credential.* options above can be applied selectively to some credentials.
           For example "credential.https://example.com.username" would set the default username
           only for https connections to example.com. See gitcredentials(7) for details on how
           URLs are matched.

       diff.autorefreshindex
           When using git diff to compare with work tree files, do not consider stat-only change
           as changed. Instead, silently run git update-index --refresh to update the cached stat
           information for paths whose contents in the work tree match the contents in the index.
           This option defaults to true. Note that this affects only git diff Porcelain, and not
           lower level diff commands such as git diff-files.

       diff.dirstat
           A comma separated list of --dirstat parameters specifying the default behavior of the
           --dirstat option to git-diff(1)` and friends. The defaults can be overridden on the
           command line (using --dirstat=<param1,param2,...>). The fallback defaults (when not
           changed by diff.dirstat) are changes,noncumulative,3. The following parameters are
           available:

           changes
               Compute the dirstat numbers by counting the lines that have been removed from the
               source, or added to the destination. This ignores the amount of pure code
               movements within a file. In other words, rearranging lines in a file is not
               counted as much as other changes. This is the default behavior when no parameter
               is given.

           lines
               Compute the dirstat numbers by doing the regular line-based diff analysis, and
               summing the removed/added line counts. (For binary files, count 64-byte chunks
               instead, since binary files have no natural concept of lines). This is a more
               expensive --dirstat behavior than the changes behavior, but it does count
               rearranged lines within a file as much as other changes. The resulting output is
               consistent with what you get from the other --*stat options.

           files
               Compute the dirstat numbers by counting the number of files changed. Each changed
               file counts equally in the dirstat analysis. This is the computationally cheapest
               --dirstat behavior, since it does not have to look at the file contents at all.

           cumulative
               Count changes in a child directory for the parent directory as well. Note that
               when using cumulative, the sum of the percentages reported may exceed 100%. The
               default (non-cumulative) behavior can be specified with the noncumulative
               parameter.

           <limit>
               An integer parameter specifies a cut-off percent (3% by default). Directories
               contributing less than this percentage of the changes are not shown in the output.

           Example: The following will count changed files, while ignoring directories with less
           than 10% of the total amount of changed files, and accumulating child directory counts
           in the parent directories: files,10,cumulative.

       diff.statGraphWidth
           Limit the width of the graph part in --stat output. If set, applies to all commands
           generating --stat output except format-patch.

       diff.context
           Generate diffs with <n> lines of context instead of the default of 3. This value is
           overridden by the -U option.

       diff.external
           If this config variable is set, diff generation is not performed using the internal
           diff machinery, but using the given command. Can be overridden with the
           ‘GIT_EXTERNAL_DIFF’ environment variable. The command is called with parameters as
           described under "git Diffs" in git(1). Note: if you want to use an external diff
           program only on a subset of your files, you might want to use gitattributes(5)
           instead.

       diff.ignoreSubmodules
           Sets the default value of --ignore-submodules. Note that this affects only git diff
           Porcelain, and not lower level diff commands such as git diff-files.  git checkout
           also honors this setting when reporting uncommitted changes. Setting it to all
           disables the submodule summary normally shown by git commit and git status when
           status.submodulesummary is set unless it is overridden by using the
           --ignore-submodules command-line option. The git submodule commands are not affected
           by this setting.

       diff.mnemonicprefix
           If set, git diff uses a prefix pair that is different from the standard "a/" and "b/"
           depending on what is being compared. When this configuration is in effect, reverse
           diff output also swaps the order of the prefixes:

           git diff
               compares the (i)ndex and the (w)ork tree;

           git diff HEAD
               compares a (c)ommit and the (w)ork tree;

           git diff --cached
               compares a (c)ommit and the (i)ndex;

           git diff HEAD:file1 file2
               compares an (o)bject and a (w)ork tree entity;

           git diff --no-index a b
               compares two non-git things (1) and (2).

       diff.noprefix
           If set, git diff does not show any source or destination prefix.

       diff.orderfile
           File indicating how to order files within a diff, using one shell glob pattern per
           line. Can be overridden by the -O option to git-diff(1).

       diff.renameLimit
           The number of files to consider when performing the copy/rename detection; equivalent
           to the git diff option -l.

       diff.renames
           Tells Git to detect renames. If set to any boolean value, it will enable basic rename
           detection. If set to "copies" or "copy", it will detect copies, as well.

       diff.suppressBlankEmpty
           A boolean to inhibit the standard behavior of printing a space before each empty
           output line. Defaults to false.

       diff.submodule
           Specify the format in which differences in submodules are shown. The "log" format
           lists the commits in the range like git-submodule(1)summary does. The "short" format
           format just shows the names of the commits at the beginning and end of the range.
           Defaults to short.

       diff.wordRegex
           A POSIX Extended Regular Expression used to determine what is a "word" when performing
           word-by-word difference calculations. Character sequences that match the regular
           expression are "words", all other characters are ignorable whitespace.

       diff.<driver>.command
           The custom diff driver command. See gitattributes(5) for details.

       diff.<driver>.xfuncname
           The regular expression that the diff driver should use to recognize the hunk header. A
           built-in pattern may also be used. See gitattributes(5) for details.

       diff.<driver>.binary
           Set this option to true to make the diff driver treat files as binary. See
           gitattributes(5) for details.

       diff.<driver>.textconv
           The command that the diff driver should call to generate the text-converted version of
           a file. The result of the conversion is used to generate a human-readable diff. See
           gitattributes(5) for details.

       diff.<driver>.wordregex
           The regular expression that the diff driver should use to split words in a line. See
           gitattributes(5) for details.

       diff.<driver>.cachetextconv
           Set this option to true to make the diff driver cache the text conversion outputs. See
           gitattributes(5) for details.

       diff.tool
           Controls which diff tool is used by git-difftool(1). This variable overrides the value
           configured in merge.tool. The list below shows the valid built-in values. Any other
           value is treated as a custom diff tool and requires that a corresponding
           difftool.<tool>.cmd variable is defined.

       diff.algorithm
           Choose a diff algorithm. The variants are as follows:

           default, myers
               The basic greedy diff algorithm. Currently, this is the default.

           minimal
               Spend extra time to make sure the smallest possible diff is produced.

           patience
               Use "patience diff" algorithm when generating patches.

           histogram
               This algorithm extends the patience algorithm to "support low-occurrence common
               elements".

       difftool.<tool>.path
           Override the path for the given tool. This is useful in case your tool is not in the
           PATH.

       difftool.<tool>.cmd
           Specify the command to invoke the specified diff tool. The specified command is
           evaluated in shell with the following variables available: LOCAL is set to the name of
           the temporary file containing the contents of the diff pre-image and REMOTE is set to
           the name of the temporary file containing the contents of the diff post-image.

       difftool.prompt
           Prompt before each invocation of the diff tool.

       fetch.recurseSubmodules
           This option can be either set to a boolean value or to on-demand. Setting it to a
           boolean changes the behavior of fetch and pull to unconditionally recurse into
           submodules when set to true or to not recurse at all when set to false. When set to
           on-demand (the default value), fetch and pull will only recurse into a populated
           submodule when its superproject retrieves a commit that updates the submodule’s
           reference.

       fetch.fsckObjects
           If it is set to true, git-fetch-pack will check all fetched objects. It will abort in
           the case of a malformed object or a broken link. The result of an abort are only
           dangling objects. Defaults to false. If not set, the value of transfer.fsckObjects is
           used instead.

       fetch.unpackLimit
           If the number of objects fetched over the Git native transfer is below this limit,
           then the objects will be unpacked into loose object files. However if the number of
           received objects equals or exceeds this limit then the received pack will be stored as
           a pack, after adding any missing delta bases. Storing the pack from a push can make
           the push operation complete faster, especially on slow filesystems. If not set, the
           value of transfer.unpackLimit is used instead.

       fetch.prune
           If true, fetch will automatically behave as if the --prune option was given on the
           command line. See also remote.<name>.prune.

       format.attach
           Enable multipart/mixed attachments as the default for format-patch. The value can also
           be a double quoted string which will enable attachments as the default and set the
           value as the boundary. See the --attach option in git-format-patch(1).

       format.numbered
           A boolean which can enable or disable sequence numbers in patch subjects. It defaults
           to "auto" which enables it only if there is more than one patch. It can be enabled or
           disabled for all messages by setting it to "true" or "false". See --numbered option in
           git-format-patch(1).

       format.headers
           Additional email headers to include in a patch to be submitted by mail. See git-
           format-patch(1).

       format.to, format.cc
           Additional recipients to include in a patch to be submitted by mail. See the --to and
           --cc options in git-format-patch(1).

       format.subjectprefix
           The default for format-patch is to output files with the [PATCH] subject prefix. Use
           this variable to change that prefix.

       format.signature
           The default for format-patch is to output a signature containing the Git version
           number. Use this variable to change that default. Set this variable to the empty
           string ("") to suppress signature generation.

       format.signaturefile
           Works just like format.signature except the contents of the file specified by this
           variable will be used as the signature.

       format.suffix
           The default for format-patch is to output files with the suffix .patch. Use this
           variable to change that suffix (make sure to include the dot if you want it).

       format.pretty
           The default pretty format for log/show/whatchanged command, See git-log(1), git-
           show(1), git-whatchanged(1).

       format.thread
           The default threading style for git format-patch. Can be a boolean value, or shallow
           or deep.  shallow threading makes every mail a reply to the head of the series, where
           the head is chosen from the cover letter, the --in-reply-to, and the first patch mail,
           in this order.  deep threading makes every mail a reply to the previous one. A true
           boolean value is the same as shallow, and a false value disables threading.

       format.signoff
           A boolean value which lets you enable the -s/--signoff option of format-patch by
           default.  Note: Adding the Signed-off-by: line to a patch should be a conscious act
           and means that you certify you have the rights to submit this work under the same open
           source license. Please see the SubmittingPatches document for further discussion.

       format.coverLetter
           A boolean that controls whether to generate a cover-letter when format-patch is
           invoked, but in addition can be set to "auto", to generate a cover-letter only when
           there’s more than one patch.

       filter.<driver>.clean
           The command which is used to convert the content of a worktree file to a blob upon
           checkin. See gitattributes(5) for details.

       filter.<driver>.smudge
           The command which is used to convert the content of a blob object to a worktree file
           upon checkout. See gitattributes(5) for details.

       gc.aggressiveDepth
           The depth parameter used in the delta compression algorithm used by git gc
           --aggressive. This defaults to 250.

       gc.aggressiveWindow
           The window size parameter used in the delta compression algorithm used by git gc
           --aggressive. This defaults to 250.

       gc.auto
           When there are approximately more than this many loose objects in the repository, git
           gc --auto will pack them. Some Porcelain commands use this command to perform a
           light-weight garbage collection from time to time. The default value is 6700. Setting
           this to 0 disables it.

       gc.autopacklimit
           When there are more than this many packs that are not marked with *.keep file in the
           repository, git gc --auto consolidates them into one larger pack. The default value is
           50. Setting this to 0 disables it.

       gc.autodetach
           Make git gc --auto return immediately andrun in background if the system supports it.
           Default is true.

       gc.packrefs
           Running git pack-refs in a repository renders it unclonable by Git versions prior to
           1.5.1.2 over dumb transports such as HTTP. This variable determines whether git gc
           runs git pack-refs. This can be set to notbare to enable it within all non-bare repos
           or it can be set to a boolean value. The default is true.

       gc.pruneexpire
           When git gc is run, it will call prune --expire 2.weeks.ago. Override the grace period
           with this config variable. The value "now" may be used to disable this grace period
           and always prune unreachable objects immediately.

       gc.reflogexpire, gc.<pattern>.reflogexpire
           git reflog expire removes reflog entries older than this time; defaults to 90 days.
           With "<pattern>" (e.g. "refs/stash") in the middle the setting applies only to the
           refs that match the <pattern>.

       gc.reflogexpireunreachable, gc.<ref>.reflogexpireunreachable
           git reflog expire removes reflog entries older than this time and are not reachable
           from the current tip; defaults to 30 days. With "<pattern>" (e.g. "refs/stash") in the
           middle, the setting applies only to the refs that match the <pattern>.

       gc.rerereresolved
           Records of conflicted merge you resolved earlier are kept for this many days when git
           rerere gc is run. The default is 60 days. See git-rerere(1).

       gc.rerereunresolved
           Records of conflicted merge you have not resolved are kept for this many days when git
           rerere gc is run. The default is 15 days. See git-rerere(1).

       gitcvs.commitmsgannotation
           Append this string to each commit message. Set to empty string to disable this
           feature. Defaults to "via git-CVS emulator".

       gitcvs.enabled
           Whether the CVS server interface is enabled for this repository. See git-cvsserver(1).

       gitcvs.logfile
           Path to a log file where the CVS server interface well... logs various stuff. See git-
           cvsserver(1).

       gitcvs.usecrlfattr
           If true, the server will look up the end-of-line conversion attributes for files to
           determine the -k modes to use. If the attributes force Git to treat a file as text,
           the -k mode will be left blank so CVS clients will treat it as text. If they suppress
           text conversion, the file will be set with -kb mode, which suppresses any newline
           munging the client might otherwise do. If the attributes do not allow the file type to
           be determined, then gitcvs.allbinary is used. See gitattributes(5).

       gitcvs.allbinary
           This is used if gitcvs.usecrlfattr does not resolve the correct -kb mode to use. If
           true, all unresolved files are sent to the client in mode -kb. This causes the client
           to treat them as binary files, which suppresses any newline munging it otherwise might
           do. Alternatively, if it is set to "guess", then the contents of the file are examined
           to decide if it is binary, similar to core.autocrlf.

       gitcvs.dbname
           Database used by git-cvsserver to cache revision information derived from the Git
           repository. The exact meaning depends on the used database driver, for SQLite (which
           is the default driver) this is a filename. Supports variable substitution (see git-
           cvsserver(1) for details). May not contain semicolons (;). Default: %Ggitcvs.%m.sqlite

       gitcvs.dbdriver
           Used Perl DBI driver. You can specify any available driver for this here, but it might
           not work. git-cvsserver is tested with DBD::SQLite, reported to work with DBD::Pg, and
           reported not to work with DBD::mysql. Experimental feature. May not contain double
           colons (:). Default: SQLite. See git-cvsserver(1).

       gitcvs.dbuser, gitcvs.dbpass
           Database user and password. Only useful if setting gitcvs.dbdriver, since SQLite has
           no concept of database users and/or passwords.  gitcvs.dbuser supports variable
           substitution (see git-cvsserver(1) for details).

       gitcvs.dbTableNamePrefix
           Database table name prefix. Prepended to the names of any database tables used,
           allowing a single database to be used for several repositories. Supports variable
           substitution (see git-cvsserver(1) for details). Any non-alphabetic characters will be
           replaced with underscores.

       All gitcvs variables except for gitcvs.usecrlfattr and gitcvs.allbinary can also be
       specified as gitcvs.<access_method>.<varname> (where access_method is one of "ext" and
       "pserver") to make them apply only for the given access method.

       gitweb.category, gitweb.description, gitweb.owner, gitweb.url
           See gitweb(1) for description.

       gitweb.avatar, gitweb.blame, gitweb.grep, gitweb.highlight, gitweb.patches,
       gitweb.pickaxe, gitweb.remote_heads, gitweb.showsizes, gitweb.snapshot
           See gitweb.conf(5) for description.

       grep.lineNumber
           If set to true, enable -n option by default.

       grep.patternType
           Set the default matching behavior. Using a value of basic, extended, fixed, or perl
           will enable the --basic-regexp, --extended-regexp, --fixed-strings, or --perl-regexp
           option accordingly, while the value default will return to the default matching
           behavior.

       grep.extendedRegexp
           If set to true, enable --extended-regexp option by default. This option is ignored
           when the grep.patternType option is set to a value other than default.

       gpg.program
           Use this custom program instead of "gpg" found on $PATH when making or verifying a PGP
           signature. The program must support the same command-line interface as GPG, namely, to
           verify a detached signature, "gpg --verify $file - <$signature" is run, and the
           program is expected to signal a good signature by exiting with code 0, and to generate
           an ascii-armored detached signature, the standard input of "gpg -bsau $key" is fed
           with the contents to be signed, and the program is expected to send the result to its
           standard output.

       gui.commitmsgwidth
           Defines how wide the commit message window is in the git-gui(1). "75" is the default.

       gui.diffcontext
           Specifies how many context lines should be used in calls to diff made by the git-
           gui(1). The default is "5".

       gui.displayuntracked
           Determines if :git-gui(1) shows untracked files in the file list. The default is
           "true".

       gui.encoding
           Specifies the default encoding to use for displaying of file contents in git-gui(1)
           and gitk(1). It can be overridden by setting the encoding attribute for relevant files
           (see gitattributes(5)). If this option is not set, the tools default to the locale
           encoding.

       gui.matchtrackingbranch
           Determines if new branches created with git-gui(1) should default to tracking remote
           branches with matching names or not. Default: "false".

       gui.newbranchtemplate
           Is used as suggested name when creating new branches using the git-gui(1).

       gui.pruneduringfetch
           "true" if git-gui(1) should prune remote-tracking branches when performing a fetch.
           The default value is "false".

       gui.trustmtime
           Determines if git-gui(1) should trust the file modification timestamp or not. By
           default the timestamps are not trusted.

       gui.spellingdictionary
           Specifies the dictionary used for spell checking commit messages in the git-gui(1).
           When set to "none" spell checking is turned off.

       gui.fastcopyblame
           If true, git gui blame uses -C instead of -C -C for original location detection. It
           makes blame significantly faster on huge repositories at the expense of less thorough
           copy detection.

       gui.copyblamethreshold
           Specifies the threshold to use in git gui blame original location detection, measured
           in alphanumeric characters. See the git-blame(1) manual for more information on copy
           detection.

       gui.blamehistoryctx
           Specifies the radius of history context in days to show in gitk(1) for the selected
           commit, when the Show History Context menu item is invoked from git gui blame. If this
           variable is set to zero, the whole history is shown.

       guitool.<name>.cmd
           Specifies the shell command line to execute when the corresponding item of the git-
           gui(1)Tools menu is invoked. This option is mandatory for every tool. The command is
           executed from the root of the working directory, and in the environment it receives
           the name of the tool as GIT_GUITOOL, the name of the currently selected file as
           FILENAME, and the name of the current branch as CUR_BRANCH (if the head is detached,
           CUR_BRANCH is empty).

       guitool.<name>.needsfile
           Run the tool only if a diff is selected in the GUI. It guarantees that FILENAME is not
           empty.

       guitool.<name>.noconsole
           Run the command silently, without creating a window to display its output.

       guitool.<name>.norescan
           Don’t rescan the working directory for changes after the tool finishes execution.

       guitool.<name>.confirm
           Show a confirmation dialog before actually running the tool.

       guitool.<name>.argprompt
           Request a string argument from the user, and pass it to the tool through the ARGS
           environment variable. Since requesting an argument implies confirmation, the confirm
           option has no effect if this is enabled. If the option is set to true, yes, or 1, the
           dialog uses a built-in generic prompt; otherwise the exact value of the variable is
           used.

       guitool.<name>.revprompt
           Request a single valid revision from the user, and set the REVISION environment
           variable. In other aspects this option is similar to argprompt, and can be used
           together with it.

       guitool.<name>.revunmerged
           Show only unmerged branches in the revprompt subdialog. This is useful for tools
           similar to merge or rebase, but not for things like checkout or reset.

       guitool.<name>.title
           Specifies the title to use for the prompt dialog. The default is the tool name.

       guitool.<name>.prompt
           Specifies the general prompt string to display at the top of the dialog, before
           subsections for argprompt and revprompt. The default value includes the actual
           command.

       help.browser
           Specify the browser that will be used to display help in the web format. See git-
           help(1).

       help.format
           Override the default help format used by git-help(1). Values man, info, web and html
           are supported.  man is the default.  web and html are the same.

       help.autocorrect
           Automatically correct and execute mistyped commands after waiting for the given number
           of deciseconds (0.1 sec). If more than one command can be deduced from the entered
           text, nothing will be executed. If the value of this option is negative, the corrected
           command will be executed immediately. If the value is 0 - the command will be just
           shown but not executed. This is the default.

       help.htmlpath
           Specify the path where the HTML documentation resides. File system paths and URLs are
           supported. HTML pages will be prefixed with this path when help is displayed in the
           web format. This defaults to the documentation path of your Git installation.

       http.proxy
           Override the HTTP proxy, normally configured using the http_proxy, https_proxy, and
           all_proxy environment variables (see curl(1)). This can be overridden on a per-remote
           basis; see remote.<name>.proxy

       http.cookiefile
           File containing previously stored cookie lines which should be used in the Git http
           session, if they match the server. The file format of the file to read cookies from
           should be plain HTTP headers or the Netscape/Mozilla cookie file format (see curl(1)).
           NOTE that the file specified with http.cookiefile is only used as input unless
           http.saveCookies is set.

       http.savecookies
           If set, store cookies received during requests to the file specified by
           http.cookiefile. Has no effect if http.cookiefile is unset.

       http.sslVerify
           Whether to verify the SSL certificate when fetching or pushing over HTTPS. Can be
           overridden by the GIT_SSL_NO_VERIFY environment variable.

       http.sslCert
           File containing the SSL certificate when fetching or pushing over HTTPS. Can be
           overridden by the GIT_SSL_CERT environment variable.

       http.sslKey
           File containing the SSL private key when fetching or pushing over HTTPS. Can be
           overridden by the GIT_SSL_KEY environment variable.

       http.sslCertPasswordProtected
           Enable Git’s password prompt for the SSL certificate. Otherwise OpenSSL will prompt
           the user, possibly many times, if the certificate or private key is encrypted. Can be
           overridden by the GIT_SSL_CERT_PASSWORD_PROTECTED environment variable.

       http.sslCAInfo
           File containing the certificates to verify the peer with when fetching or pushing over
           HTTPS. Can be overridden by the GIT_SSL_CAINFO environment variable.

       http.sslCAPath
           Path containing files with the CA certificates to verify the peer with when fetching
           or pushing over HTTPS. Can be overridden by the GIT_SSL_CAPATH environment variable.

       http.sslTry
           Attempt to use AUTH SSL/TLS and encrypted data transfers when connecting via regular
           FTP protocol. This might be needed if the FTP server requires it for security reasons
           or you wish to connect securely whenever remote FTP server supports it. Default is
           false since it might trigger certificate verification errors on misconfigured servers.

       http.maxRequests
           How many HTTP requests to launch in parallel. Can be overridden by the
           GIT_HTTP_MAX_REQUESTS environment variable. Default is 5.

       http.minSessions
           The number of curl sessions (counted across slots) to be kept across requests. They
           will not be ended with curl_easy_cleanup() until http_cleanup() is invoked. If
           USE_CURL_MULTI is not defined, this value will be capped at 1. Defaults to 1.

       http.postBuffer
           Maximum size in bytes of the buffer used by smart HTTP transports when POSTing data to
           the remote system. For requests larger than this buffer size, HTTP/1.1 and
           Transfer-Encoding: chunked is used to avoid creating a massive pack file locally.
           Default is 1 MiB, which is sufficient for most requests.

       http.lowSpeedLimit, http.lowSpeedTime
           If the HTTP transfer speed is less than http.lowSpeedLimit for longer than
           http.lowSpeedTime seconds, the transfer is aborted. Can be overridden by the
           GIT_HTTP_LOW_SPEED_LIMIT and GIT_HTTP_LOW_SPEED_TIME environment variables.

       http.noEPSV
           A boolean which disables using of EPSV ftp command by curl. This can helpful with some
           "poor" ftp servers which don’t support EPSV mode. Can be overridden by the
           GIT_CURL_FTP_NO_EPSV environment variable. Default is false (curl will use EPSV).

       http.useragent
           The HTTP USER_AGENT string presented to an HTTP server. The default value represents
           the version of the client Git such as git/1.7.1. This option allows you to override
           this value to a more common value such as Mozilla/4.0. This may be necessary, for
           instance, if connecting through a firewall that restricts HTTP connections to a set of
           common USER_AGENT strings (but not including those like git/1.7.1). Can be overridden
           by the GIT_HTTP_USER_AGENT environment variable.

       http.<url>.*
           Any of the http.* options above can be applied selectively to some urls. For a config
           key to match a URL, each element of the config key is compared to that of the URL, in
           the following order:

            1. Scheme (e.g., https in https://example.com/). This field must match exactly
               between the config key and the URL.

            2. Host/domain name (e.g., example.com in https://example.com/). This field must
               match exactly between the config key and the URL.

            3. Port number (e.g., 8080 in http://example.com:8080/). This field must match
               exactly between the config key and the URL. Omitted port numbers are automatically
               converted to the correct default for the scheme before matching.

            4. Path (e.g., repo.git in https://example.com/repo.git). The path field of the
               config key must match the path field of the URL either exactly or as a prefix of
               slash-delimited path elements. This means a config key with path foo/ matches URL
               path foo/bar. A prefix can only match on a slash (/) boundary. Longer matches take
               precedence (so a config key with path foo/bar is a better match to URL path
               foo/bar than a config key with just path foo/).

            5. User name (e.g., user in https://user AT example.com/repo.git). If the config key has
               a user name it must match the user name in the URL exactly. If the config key does
               not have a user name, that config key will match a URL with any user name
               (including none), but at a lower precedence than a config key with a user name.

           The list above is ordered by decreasing precedence; a URL that matches a config key’s
           path is preferred to one that matches its user name. For example, if the URL is
           https://user AT example.com/foo/bar a config key match of https://example.com/foo will be
           preferred over a config key match of https://user AT example.com.

           All URLs are normalized before attempting any matching (the password part, if embedded
           in the URL, is always ignored for matching purposes) so that equivalent urls that are
           simply spelled differently will match properly. Environment variable settings always
           override any matches. The urls that are matched against are those given directly to
           Git commands. This means any URLs visited as a result of a redirection do not
           participate in matching.

       i18n.commitEncoding
           Character encoding the commit messages are stored in; Git itself does not care per se,
           but this information is necessary e.g. when importing commits from emails or in the
           gitk graphical history browser (and possibly at other places in the future or in other
           porcelains). See e.g.  git-mailinfo(1). Defaults to utf-8.

       i18n.logOutputEncoding
           Character encoding the commit messages are converted to when running git log and
           friends.

       imap
           The configuration variables in the imap section are described in git-imap-send(1).

       index.version
           Specify the version with which new index files should be initialized. This does not
           affect existing repositories.

       init.templatedir
           Specify the directory from which templates will be copied. (See the "TEMPLATE
           DIRECTORY" section of git-init(1).)

       instaweb.browser
           Specify the program that will be used to browse your working repository in gitweb. See
           git-instaweb(1).

       instaweb.httpd
           The HTTP daemon command-line to start gitweb on your working repository. See git-
           instaweb(1).

       instaweb.local
           If true the web server started by git-instaweb(1) will be bound to the local IP
           (127.0.0.1).

       instaweb.modulepath
           The default module path for git-instaweb(1) to use instead of
           /usr/lib/apache2/modules. Only used if httpd is Apache.

       instaweb.port
           The port number to bind the gitweb httpd to. See git-instaweb(1).

       interactive.singlekey
           In interactive commands, allow the user to provide one-letter input with a single key
           (i.e., without hitting enter). Currently this is used by the --patch mode of git-
           add(1), git-checkout(1), git-commit(1), git-reset(1), and git-stash(1). Note that this
           setting is silently ignored if portable keystroke input is not available; requires the
           Perl module Term::ReadKey.

       log.abbrevCommit
           If true, makes git-log(1), git-show(1), and git-whatchanged(1) assume --abbrev-commit.
           You may override this option with --no-abbrev-commit.

       log.date
           Set the default date-time mode for the log command. Setting a value for log.date is
           similar to using git log's --date option. Possible values are relative, local,
           default, iso, rfc, and short; see git-log(1) for details.

       log.decorate
           Print out the ref names of any commits that are shown by the log command. If short is
           specified, the ref name prefixes refs/heads/, refs/tags/ and refs/remotes/ will not be
           printed. If full is specified, the full ref name (including prefix) will be printed.
           This is the same as the log commands --decorate option.

       log.showroot
           If true, the initial commit will be shown as a big creation event. This is equivalent
           to a diff against an empty tree. Tools like git-log(1) or git-whatchanged(1), which
           normally hide the root commit will now show it. True by default.

       log.mailmap
           If true, makes git-log(1), git-show(1), and git-whatchanged(1) assume --use-mailmap.

       mailmap.file
           The location of an augmenting mailmap file. The default mailmap, located in the root
           of the repository, is loaded first, then the mailmap file pointed to by this variable.
           The location of the mailmap file may be in a repository subdirectory, or somewhere
           outside of the repository itself. See git-shortlog(1) and git-blame(1).

       mailmap.blob
           Like mailmap.file, but consider the value as a reference to a blob in the repository.
           If both mailmap.file and mailmap.blob are given, both are parsed, with entries from
           mailmap.file taking precedence. In a bare repository, this defaults to HEAD:.mailmap.
           In a non-bare repository, it defaults to empty.

       man.viewer
           Specify the programs that may be used to display help in the man format. See git-
           help(1).

       man.<tool>.cmd
           Specify the command to invoke the specified man viewer. The specified command is
           evaluated in shell with the man page passed as argument. (See git-help(1).)

       man.<tool>.path
           Override the path for the given tool that may be used to display help in the man
           format. See git-help(1).

       merge.conflictstyle
           Specify the style in which conflicted hunks are written out to working tree files upon
           merge. The default is "merge", which shows a <<<<<<< conflict marker, changes made by
           one side, a ======= marker, changes made by the other side, and then a >>>>>>> marker.
           An alternate style, "diff3", adds a ||||||| marker and the original text before the
           ======= marker.

       merge.defaultToUpstream
           If merge is called without any commit argument, merge the upstream branches configured
           for the current branch by using their last observed values stored in their
           remote-tracking branches. The values of the branch.<current branch>.merge that name
           the branches at the remote named by branch.<current branch>.remote are consulted, and
           then they are mapped via remote.<remote>.fetch to their corresponding remote-tracking
           branches, and the tips of these tracking branches are merged.

       merge.ff
           By default, Git does not create an extra merge commit when merging a commit that is a
           descendant of the current commit. Instead, the tip of the current branch is
           fast-forwarded. When set to false, this variable tells Git to create an extra merge
           commit in such a case (equivalent to giving the --no-ff option from the command line).
           When set to only, only such fast-forward merges are allowed (equivalent to giving the
           --ff-only option from the command line).

       merge.log
           In addition to branch names, populate the log message with at most the specified
           number of one-line descriptions from the actual commits that are being merged.
           Defaults to false, and true is a synonym for 20.

       merge.renameLimit
           The number of files to consider when performing rename detection during a merge; if
           not specified, defaults to the value of diff.renameLimit.

       merge.renormalize
           Tell Git that canonical representation of files in the repository has changed over
           time (e.g. earlier commits record text files with CRLF line endings, but recent ones
           use LF line endings). In such a repository, Git can convert the data recorded in
           commits to a canonical form before performing a merge to reduce unnecessary conflicts.
           For more information, see section "Merging branches with differing checkin/checkout
           attributes" in gitattributes(5).

       merge.stat
           Whether to print the diffstat between ORIG_HEAD and the merge result at the end of the
           merge. True by default.

       merge.tool
           Controls which merge tool is used by git-mergetool(1). The list below shows the valid
           built-in values. Any other value is treated as a custom merge tool and requires that a
           corresponding mergetool.<tool>.cmd variable is defined.

       merge.verbosity
           Controls the amount of output shown by the recursive merge strategy. Level 0 outputs
           nothing except a final error message if conflicts were detected. Level 1 outputs only
           conflicts, 2 outputs conflicts and file changes. Level 5 and above outputs debugging
           information. The default is level 2. Can be overridden by the GIT_MERGE_VERBOSITY
           environment variable.

       merge.<driver>.name
           Defines a human-readable name for a custom low-level merge driver. See
           gitattributes(5) for details.

       merge.<driver>.driver
           Defines the command that implements a custom low-level merge driver. See
           gitattributes(5) for details.

       merge.<driver>.recursive
           Names a low-level merge driver to be used when performing an internal merge between
           common ancestors. See gitattributes(5) for details.

       mergetool.<tool>.path
           Override the path for the given tool. This is useful in case your tool is not in the
           PATH.

       mergetool.<tool>.cmd
           Specify the command to invoke the specified merge tool. The specified command is
           evaluated in shell with the following variables available: BASE is the name of a
           temporary file containing the common base of the files to be merged, if available;
           LOCAL is the name of a temporary file containing the contents of the file on the
           current branch; REMOTE is the name of a temporary file containing the contents of the
           file from the branch being merged; MERGED contains the name of the file to which the
           merge tool should write the results of a successful merge.

       mergetool.<tool>.trustExitCode
           For a custom merge command, specify whether the exit code of the merge command can be
           used to determine whether the merge was successful. If this is not set to true then
           the merge target file timestamp is checked and the merge assumed to have been
           successful if the file has been updated, otherwise the user is prompted to indicate
           the success of the merge.

       mergetool.meld.hasOutput
           Older versions of meld do not support the --output option. Git will attempt to detect
           whether meld supports --output by inspecting the output of meld --help. Configuring
           mergetool.meld.hasOutput will make Git skip these checks and use the configured value
           instead. Setting mergetool.meld.hasOutput to true tells Git to unconditionally use the
           --output option, and false avoids using --output.

       mergetool.keepBackup
           After performing a merge, the original file with conflict markers can be saved as a
           file with a .orig extension. If this variable is set to false then this file is not
           preserved. Defaults to true (i.e. keep the backup files).

       mergetool.keepTemporaries
           When invoking a custom merge tool, Git uses a set of temporary files to pass to the
           tool. If the tool returns an error and this variable is set to true, then these
           temporary files will be preserved, otherwise they will be removed after the tool has
           exited. Defaults to false.

       mergetool.prompt
           Prompt before each invocation of the merge resolution program.

       notes.displayRef
           The (fully qualified) refname from which to show notes when showing commit messages.
           The value of this variable can be set to a glob, in which case notes from all matching
           refs will be shown. You may also specify this configuration variable several times. A
           warning will be issued for refs that do not exist, but a glob that does not match any
           refs is silently ignored.

           This setting can be overridden with the GIT_NOTES_DISPLAY_REF environment variable,
           which must be a colon separated list of refs or globs.

           The effective value of "core.notesRef" (possibly overridden by GIT_NOTES_REF) is also
           implicitly added to the list of refs to be displayed.

       notes.rewrite.<command>
           When rewriting commits with <command> (currently amend or rebase) and this variable is
           set to true, Git automatically copies your notes from the original to the rewritten
           commit. Defaults to true, but see "notes.rewriteRef" below.

       notes.rewriteMode
           When copying notes during a rewrite (see the "notes.rewrite.<command>" option),
           determines what to do if the target commit already has a note. Must be one of
           overwrite, concatenate, or ignore. Defaults to concatenate.

           This setting can be overridden with the GIT_NOTES_REWRITE_MODE environment variable.

       notes.rewriteRef
           When copying notes during a rewrite, specifies the (fully qualified) ref whose notes
           should be copied. The ref may be a glob, in which case notes in all matching refs will
           be copied. You may also specify this configuration several times.

           Does not have a default value; you must configure this variable to enable note
           rewriting. Set it to refs/notes/commits to enable rewriting for the default commit
           notes.

           This setting can be overridden with the GIT_NOTES_REWRITE_REF environment variable,
           which must be a colon separated list of refs or globs.

       pack.window
           The size of the window used by git-pack-objects(1) when no window size is given on the
           command line. Defaults to 10.

       pack.depth
           The maximum delta depth used by git-pack-objects(1) when no maximum depth is given on
           the command line. Defaults to 50.

       pack.windowMemory
           The window memory size limit used by git-pack-objects(1) when no limit is given on the
           command line. The value can be suffixed with "k", "m", or "g". Defaults to 0, meaning
           no limit.

       pack.compression
           An integer -1..9, indicating the compression level for objects in a pack file. -1 is
           the zlib default. 0 means no compression, and 1..9 are various speed/size tradeoffs, 9
           being slowest. If not set, defaults to core.compression. If that is not set, defaults
           to -1, the zlib default, which is "a default compromise between speed and compression
           (currently equivalent to level 6)."

           Note that changing the compression level will not automatically recompress all
           existing objects. You can force recompression by passing the -F option to git-
           repack(1).

       pack.deltaCacheSize
           The maximum memory in bytes used for caching deltas in git-pack-objects(1) before
           writing them out to a pack. This cache is used to speed up the writing object phase by
           not having to recompute the final delta result once the best match for all objects is
           found. Repacking large repositories on machines which are tight with memory might be
           badly impacted by this though, especially if this cache pushes the system into
           swapping. A value of 0 means no limit. The smallest size of 1 byte may be used to
           virtually disable this cache. Defaults to 256 MiB.

       pack.deltaCacheLimit
           The maximum size of a delta, that is cached in git-pack-objects(1). This cache is used
           to speed up the writing object phase by not having to recompute the final delta result
           once the best match for all objects is found. Defaults to 1000.

       pack.threads
           Specifies the number of threads to spawn when searching for best delta matches. This
           requires that git-pack-objects(1) be compiled with pthreads otherwise this option is
           ignored with a warning. This is meant to reduce packing time on multiprocessor
           machines. The required amount of memory for the delta search window is however
           multiplied by the number of threads. Specifying 0 will cause Git to auto-detect the
           number of CPU’s and set the number of threads accordingly.

       pack.indexVersion
           Specify the default pack index version. Valid values are 1 for legacy pack index used
           by Git versions prior to 1.5.2, and 2 for the new pack index with capabilities for
           packs larger than 4 GB as well as proper protection against the repacking of corrupted
           packs. Version 2 is the default. Note that version 2 is enforced and this config
           option ignored whenever the corresponding pack is larger than 2 GB.

           If you have an old Git that does not understand the version 2 *.idx file, cloning or
           fetching over a non native protocol (e.g. "http" and "rsync") that will copy both
           *.pack file and corresponding *.idx file from the other side may give you a repository
           that cannot be accessed with your older version of Git. If the *.pack file is smaller
           than 2 GB, however, you can use git-index-pack(1) on the *.pack file to regenerate the
           *.idx file.

       pack.packSizeLimit
           The maximum size of a pack. This setting only affects packing to a file when
           repacking, i.e. the git:// protocol is unaffected. It can be overridden by the
           --max-pack-size option of git-repack(1). The minimum size allowed is limited to 1 MiB.
           The default is unlimited. Common unit suffixes of k, m, or g are supported.

       pack.useBitmaps
           When true, git will use pack bitmaps (if available) when packing to stdout (e.g.,
           during the server side of a fetch). Defaults to true. You should not generally need to
           turn this off unless you are debugging pack bitmaps.

       pack.writebitmaps
           This is a deprecated synonym for repack.writeBitmaps.

       pack.writeBitmapHashCache
           When true, git will include a "hash cache" section in the bitmap index (if one is
           written). This cache can be used to feed git’s delta heuristics, potentially leading
           to better deltas between bitmapped and non-bitmapped objects (e.g., when serving a
           fetch between an older, bitmapped pack and objects that have been pushed since the
           last gc). The downside is that it consumes 4 bytes per object of disk space, and that
           JGit’s bitmap implementation does not understand it, causing it to complain if Git and
           JGit are used on the same repository. Defaults to false.

       pager.<cmd>
           If the value is boolean, turns on or off pagination of the output of a particular Git
           subcommand when writing to a tty. Otherwise, turns on pagination for the subcommand
           using the pager specified by the value of pager.<cmd>. If --paginate or --no-pager is
           specified on the command line, it takes precedence over this option. To disable
           pagination for all commands, set core.pager or GIT_PAGER to cat.

       pretty.<name>
           Alias for a --pretty= format string, as specified in git-log(1). Any aliases defined
           here can be used just as the built-in pretty formats could. For example, running git
           config pretty.changelog "format:* %H %s" would cause the invocation git log
           --pretty=changelog to be equivalent to running git log "--pretty=format:* %H %s". Note
           that an alias with the same name as a built-in format will be silently ignored.

       pull.ff
           By default, Git does not create an extra merge commit when merging a commit that is a
           descendant of the current commit. Instead, the tip of the current branch is
           fast-forwarded. When set to false, this variable tells Git to create an extra merge
           commit in such a case (equivalent to giving the --no-ff option from the command line).
           When set to only, only such fast-forward merges are allowed (equivalent to giving the
           --ff-only option from the command line).

       pull.rebase
           When true, rebase branches on top of the fetched branch, instead of merging the
           default branch from the default remote when "git pull" is run. See
           "branch.<name>.rebase" for setting this on a per-branch basis.

               When preserve, also pass `--preserve-merges` along to 'git rebase'
               so that locally committed merge commits will not be flattened
               by running 'git pull'.

           NOTE: this is a possibly dangerous operation; do not use it unless you understand the
           implications (see git-rebase(1) for details).

       pull.octopus
           The default merge strategy to use when pulling multiple branches at once.

       pull.twohead
           The default merge strategy to use when pulling a single branch.

       push.default
           Defines the action git push should take if no refspec is explicitly given. Different
           values are well-suited for specific workflows; for instance, in a purely central
           workflow (i.e. the fetch source is equal to the push destination), upstream is
           probably what you want. Possible values are:

           ·   nothing - do not push anything (error out) unless a refspec is explicitly given.
               This is primarily meant for people who want to avoid mistakes by always being
               explicit.

           ·   current - push the current branch to update a branch with the same name on the
               receiving end. Works in both central and non-central workflows.

           ·   upstream - push the current branch back to the branch whose changes are usually
               integrated into the current branch (which is called @{upstream}). This mode only
               makes sense if you are pushing to the same repository you would normally pull from
               (i.e. central workflow).

           ·   simple - in centralized workflow, work like upstream with an added safety to
               refuse to push if the upstream branch’s name is different from the local one.

               When pushing to a remote that is different from the remote you normally pull from,
               work as current. This is the safest option and is suited for beginners.

               This mode has become the default in Git 2.0.

           ·   matching - push all branches having the same name on both ends. This makes the
               repository you are pushing to remember the set of branches that will be pushed out
               (e.g. if you always push maint and master there and no other branches, the
               repository you push to will have these two branches, and your local maint and
               master will be pushed there).

               To use this mode effectively, you have to make sure all the branches you would
               push out are ready to be pushed out before running git push, as the whole point of
               this mode is to allow you to push all of the branches in one go. If you usually
               finish work on only one branch and push out the result, while other branches are
               unfinished, this mode is not for you. Also this mode is not suitable for pushing
               into a shared central repository, as other people may add new branches there, or
               update the tip of existing branches outside your control.

               This used to be the default, but not since Git 2.0 (simple is the new default).

       rebase.stat
           Whether to show a diffstat of what changed upstream since the last rebase. False by
           default.

       rebase.autosquash
           If set to true enable --autosquash option by default.

       rebase.autostash
           When set to true, automatically create a temporary stash before the operation begins,
           and apply it after the operation ends. This means that you can run rebase on a dirty
           worktree. However, use with care: the final stash application after a successful
           rebase might result in non-trivial conflicts. Defaults to false.

       receive.autogc
           By default, git-receive-pack will run "git-gc --auto" after receiving data from
           git-push and updating refs. You can stop it by setting this variable to false.

       receive.fsckObjects
           If it is set to true, git-receive-pack will check all received objects. It will abort
           in the case of a malformed object or a broken link. The result of an abort are only
           dangling objects. Defaults to false. If not set, the value of transfer.fsckObjects is
           used instead.

       receive.unpackLimit
           If the number of objects received in a push is below this limit then the objects will
           be unpacked into loose object files. However if the number of received objects equals
           or exceeds this limit then the received pack will be stored as a pack, after adding
           any missing delta bases. Storing the pack from a push can make the push operation
           complete faster, especially on slow filesystems. If not set, the value of
           transfer.unpackLimit is used instead.

       receive.denyDeletes
           If set to true, git-receive-pack will deny a ref update that deletes the ref. Use this
           to prevent such a ref deletion via a push.

       receive.denyDeleteCurrent
           If set to true, git-receive-pack will deny a ref update that deletes the currently
           checked out branch of a non-bare repository.

       receive.denyCurrentBranch
           If set to true or "refuse", git-receive-pack will deny a ref update to the currently
           checked out branch of a non-bare repository. Such a push is potentially dangerous
           because it brings the HEAD out of sync with the index and working tree. If set to
           "warn", print a warning of such a push to stderr, but allow the push to proceed. If
           set to false or "ignore", allow such pushes with no message. Defaults to "refuse".

       receive.denyNonFastForwards
           If set to true, git-receive-pack will deny a ref update which is not a fast-forward.
           Use this to prevent such an update via a push, even if that push is forced. This
           configuration variable is set when initializing a shared repository.

       receive.hiderefs
           String(s) receive-pack uses to decide which refs to omit from its initial
           advertisement. Use more than one definitions to specify multiple prefix strings. A ref
           that are under the hierarchies listed on the value of this variable is excluded, and
           is hidden when responding to git push, and an attempt to update or delete a hidden ref
           by git push is rejected.

       receive.updateserverinfo
           If set to true, git-receive-pack will run git-update-server-info after receiving data
           from git-push and updating refs.

       receive.shallowupdate
           If set to true, .git/shallow can be updated when new refs require new shallow roots.
           Otherwise those refs are rejected.

       remote.pushdefault
           The remote to push to by default. Overrides branch.<name>.remote for all branches, and
           is overridden by branch.<name>.pushremote for specific branches.

       remote.<name>.url
           The URL of a remote repository. See git-fetch(1) or git-push(1).

       remote.<name>.pushurl
           The push URL of a remote repository. See git-push(1).

       remote.<name>.proxy
           For remotes that require curl (http, https and ftp), the URL to the proxy to use for
           that remote. Set to the empty string to disable proxying for that remote.

       remote.<name>.fetch
           The default set of "refspec" for git-fetch(1). See git-fetch(1).

       remote.<name>.push
           The default set of "refspec" for git-push(1). See git-push(1).

       remote.<name>.mirror
           If true, pushing to this remote will automatically behave as if the --mirror option
           was given on the command line.

       remote.<name>.skipDefaultUpdate
           If true, this remote will be skipped by default when updating using git-fetch(1) or
           the update subcommand of git-remote(1).

       remote.<name>.skipFetchAll
           If true, this remote will be skipped by default when updating using git-fetch(1) or
           the update subcommand of git-remote(1).

       remote.<name>.receivepack
           The default program to execute on the remote side when pushing. See option
           --receive-pack of git-push(1).

       remote.<name>.uploadpack
           The default program to execute on the remote side when fetching. See option
           --upload-pack of git-fetch-pack(1).

       remote.<name>.tagopt
           Setting this value to --no-tags disables automatic tag following when fetching from
           remote <name>. Setting it to --tags will fetch every tag from remote <name>, even if
           they are not reachable from remote branch heads. Passing these flags directly to git-
           fetch(1) can override this setting. See options --tags and --no-tags of git-fetch(1).

       remote.<name>.vcs
           Setting this to a value <vcs> will cause Git to interact with the remote with the
           git-remote-<vcs> helper.

       remote.<name>.prune
           When set to true, fetching from this remote by default will also remove any
           remote-tracking references that no longer exist on the remote (as if the --prune
           option was given on the command line). Overrides fetch.prune settings, if any.

       remotes.<group>
           The list of remotes which are fetched by "git remote update <group>". See git-
           remote(1).

       repack.usedeltabaseoffset
           By default, git-repack(1) creates packs that use delta-base offset. If you need to
           share your repository with Git older than version 1.4.4, either directly or via a dumb
           protocol such as http, then you need to set this option to "false" and repack. Access
           from old Git versions over the native protocol are unaffected by this option.

       repack.packKeptObjects
           If set to true, makes git repack act as if --pack-kept-objects was passed. See git-
           repack(1) for details. Defaults to false normally, but true if a bitmap index is being
           written (either via --write-bitmap-index or repack.writeBitmaps).

       repack.writeBitmaps
           When true, git will write a bitmap index when packing all objects to disk (e.g., when
           git repack -a is run). This index can speed up the "counting objects" phase of
           subsequent packs created for clones and fetches, at the cost of some disk space and
           extra time spent on the initial repack. Defaults to false.

       rerere.autoupdate
           When set to true, git-rerere updates the index with the resulting contents after it
           cleanly resolves conflicts using previously recorded resolution. Defaults to false.

       rerere.enabled
           Activate recording of resolved conflicts, so that identical conflict hunks can be
           resolved automatically, should they be encountered again. By default, git-rerere(1) is
           enabled if there is an rr-cache directory under the $GIT_DIR, e.g. if "rerere" was
           previously used in the repository.

       sendemail.identity
           A configuration identity. When given, causes values in the sendemail.<identity>
           subsection to take precedence over values in the sendemail section. The default
           identity is the value of sendemail.identity.

       sendemail.smtpencryption
           See git-send-email(1) for description. Note that this setting is not subject to the
           identity mechanism.

       sendemail.smtpssl
           Deprecated alias for sendemail.smtpencryption = ssl.

       sendemail.smtpsslcertpath
           Path to ca-certificates (either a directory or a single file). Set it to an empty
           string to disable certificate verification.

       sendemail.<identity>.*
           Identity-specific versions of the sendemail.*  parameters found below, taking
           precedence over those when the this identity is selected, through command-line or
           sendemail.identity.

       sendemail.aliasesfile, sendemail.aliasfiletype, sendemail.annotate, sendemail.bcc,
       sendemail.cc, sendemail.cccmd, sendemail.chainreplyto, sendemail.confirm,
       sendemail.envelopesender, sendemail.from, sendemail.multiedit, sendemail.signedoffbycc,
       sendemail.smtppass, sendemail.suppresscc, sendemail.suppressfrom, sendemail.to,
       sendemail.smtpdomain, sendemail.smtpserver, sendemail.smtpserverport,
       sendemail.smtpserveroption, sendemail.smtpuser, sendemail.thread, sendemail.validate
           See git-send-email(1) for description.

       sendemail.signedoffcc
           Deprecated alias for sendemail.signedoffbycc.

       showbranch.default
           The default set of branches for git-show-branch(1). See git-show-branch(1).

       status.relativePaths
           By default, git-status(1) shows paths relative to the current directory. Setting this
           variable to false shows paths relative to the repository root (this was the default
           for Git prior to v1.5.4).

       status.short
           Set to true to enable --short by default in git-status(1). The option --no-short takes
           precedence over this variable.

       status.branch
           Set to true to enable --branch by default in git-status(1). The option --no-branch
           takes precedence over this variable.

       status.displayCommentPrefix
           If set to true, git-status(1) will insert a comment prefix before each output line
           (starting with core.commentChar, i.e.  # by default). This was the behavior of git-
           status(1) in Git 1.8.4 and previous. Defaults to false.

       status.showUntrackedFiles
           By default, git-status(1) and git-commit(1) show files which are not currently tracked
           by Git. Directories which contain only untracked files, are shown with the directory
           name only. Showing untracked files means that Git needs to lstat() all the files in
           the whole repository, which might be slow on some systems. So, this variable controls
           how the commands displays the untracked files. Possible values are:

           ·   no - Show no untracked files.

           ·   normal - Show untracked files and directories.

           ·   all - Show also individual files in untracked directories.

           If this variable is not specified, it defaults to normal. This variable can be
           overridden with the -u|--untracked-files option of git-status(1) and git-commit(1).

       status.submodulesummary
           Defaults to false. If this is set to a non zero number or true (identical to -1 or an
           unlimited number), the submodule summary will be enabled and a summary of commits for
           modified submodules will be shown (see --summary-limit option of git-submodule(1)).
           Please note that the summary output command will be suppressed for all submodules when
           diff.ignoreSubmodules is set to all or only for those submodules where
           submodule.<name>.ignore=all. The only exception to that rule is that status and commit
           will show staged submodule changes. To also view the summary for ignored submodules
           you can either use the --ignore-submodules=dirty command-line option or the git
           submodule summary command, which shows a similar output but does not honor these
           settings.

       submodule.<name>.path, submodule.<name>.url, submodule.<name>.update
           The path within this project, URL, and the updating strategy for a submodule. These
           variables are initially populated by git submodule init; edit them to override the URL
           and other values found in the .gitmodules file. See git-submodule(1) and gitmodules(5)
           for details.

       submodule.<name>.branch
           The remote branch name for a submodule, used by git submodule update --remote. Set
           this option to override the value found in the .gitmodules file. See git-submodule(1)
           and gitmodules(5) for details.

       submodule.<name>.fetchRecurseSubmodules
           This option can be used to control recursive fetching of this submodule. It can be
           overridden by using the --[no-]recurse-submodules command-line option to "git fetch"
           and "git pull". This setting will override that from in the gitmodules(5) file.

       submodule.<name>.ignore
           Defines under what circumstances "git status" and the diff family show a submodule as
           modified. When set to "all", it will never be considered modified (but it will
           nonetheless show up in the output of status and commit when it has been staged),
           "dirty" will ignore all changes to the submodules work tree and takes only differences
           between the HEAD of the submodule and the commit recorded in the superproject into
           account. "untracked" will additionally let submodules with modified tracked files in
           their work tree show up. Using "none" (the default when this option is not set) also
           shows submodules that have untracked files in their work tree as changed. This setting
           overrides any setting made in .gitmodules for this submodule, both settings can be
           overridden on the command line by using the "--ignore-submodules" option. The git
           submodule commands are not affected by this setting.

       tag.sort
           This variable controls the sort ordering of tags when displayed by git-tag(1). Without
           the "--sort=<value>" option provided, the value of this variable will be used as the
           default.

       tar.umask
           This variable can be used to restrict the permission bits of tar archive entries. The
           default is 0002, which turns off the world write bit. The special value "user"
           indicates that the archiving user’s umask will be used instead. See umask(2) and git-
           archive(1).

       transfer.fsckObjects
           When fetch.fsckObjects or receive.fsckObjects are not set, the value of this variable
           is used instead. Defaults to false.

       transfer.hiderefs
           This variable can be used to set both receive.hiderefs and uploadpack.hiderefs at the
           same time to the same values. See entries for these other variables.

       transfer.unpackLimit
           When fetch.unpackLimit or receive.unpackLimit are not set, the value of this variable
           is used instead. The default value is 100.

       uploadarchive.allowUnreachable
           If true, allow clients to use git archive --remote to request any tree, whether
           reachable from the ref tips or not. See the discussion in the SECURITY section of git-
           upload-archive(1) for more details. Defaults to false.

       uploadpack.hiderefs
           String(s) upload-pack uses to decide which refs to omit from its initial
           advertisement. Use more than one definitions to specify multiple prefix strings. A ref
           that are under the hierarchies listed on the value of this variable is excluded, and
           is hidden from git ls-remote, git fetch, etc. An attempt to fetch a hidden ref by git
           fetch will fail. See also uploadpack.allowtipsha1inwant.

       uploadpack.allowtipsha1inwant
           When uploadpack.hiderefs is in effect, allow upload-pack to accept a fetch request
           that asks for an object at the tip of a hidden ref (by default, such a request is
           rejected). see also uploadpack.hiderefs.

       uploadpack.keepalive
           When upload-pack has started pack-objects, there may be a quiet period while
           pack-objects prepares the pack. Normally it would output progress information, but if
           --quiet was used for the fetch, pack-objects will output nothing at all until the pack
           data begins. Some clients and networks may consider the server to be hung and give up.
           Setting this option instructs upload-pack to send an empty keepalive packet every
           uploadpack.keepalive seconds. Setting this option to 0 disables keepalive packets
           entirely. The default is 5 seconds.

       url.<base>.insteadOf
           Any URL that starts with this value will be rewritten to start, instead, with <base>.
           In cases where some site serves a large number of repositories, and serves them with
           multiple access methods, and some users need to use different access methods, this
           feature allows people to specify any of the equivalent URLs and have Git automatically
           rewrite the URL to the best alternative for the particular user, even for a
           never-before-seen repository on the site. When more than one insteadOf strings match a
           given URL, the longest match is used.

       url.<base>.pushInsteadOf
           Any URL that starts with this value will not be pushed to; instead, it will be
           rewritten to start with <base>, and the resulting URL will be pushed to. In cases
           where some site serves a large number of repositories, and serves them with multiple
           access methods, some of which do not allow push, this feature allows people to specify
           a pull-only URL and have Git automatically use an appropriate URL to push, even for a
           never-before-seen repository on the site. When more than one pushInsteadOf strings
           match a given URL, the longest match is used. If a remote has an explicit pushurl, Git
           will ignore this setting for that remote.

       user.email
           Your email address to be recorded in any newly created commits. Can be overridden by
           the GIT_AUTHOR_EMAIL, GIT_COMMITTER_EMAIL, and EMAIL environment variables. See git-
           commit-tree(1).

       user.name
           Your full name to be recorded in any newly created commits. Can be overridden by the
           GIT_AUTHOR_NAME and GIT_COMMITTER_NAME environment variables. See git-commit-tree(1).

       user.signingkey
           If git-tag(1) or git-commit(1) is not selecting the key you want it to automatically
           when creating a signed tag or commit, you can override the default selection with this
           variable. This option is passed unchanged to gpg’s --local-user parameter, so you may
           specify a key using any method that gpg supports.

       web.browser
           Specify a web browser that may be used by some commands. Currently only git-
           instaweb(1) and git-help(1) may use it.
