       terminal-colors.d - Configure output colorization for various utilities


       Files in this directory determine the default behavior for utilities when coloring output.

       The name is a utility name.  The name is optional and when none is specified then the file
       is used for all unspecified utilities.

       The term is a terminal identifier (the TERM environment variable).  The  terminal  identi‐
       fier is optional and when none is specified then the file is used for all unspecified ter‐

       The type is a file type.  Supported file types are:

              Turns off output colorization for all compatible utilities.

       enable Turns on output colorization; any matching disable files are ignored.

       scheme Specifies colors used for output.  The file format may be specific to the  utility,
              the default format is described below.

       If  there  are  more  files that match for a utility, then the file with the more specific
       filename  wins.   For  example,  the  filename  "@xterm.scheme"  has  less  priority  than
       "dmesg AT xterm.scheme".  The lowest priority are those files without a utility name and ter‐
       minal identifier (e.g. "disable").

       The user-specific  $XDG_CONFIG_HOME/terminal-colors.d  or  $HOME/.config/terminal-colors.d
       overrides the global setting.

       Disable colors for all compatible utilities:
              touch /etc/terminal-colors.d/disable

       Disable colors for all compatible utils on a vt100 terminal:
              touch /etc/terminal-colors.d/@vt100.disable

       Disable colors for all compatible utils except dmesg(1):
              touch /etc/terminal-colors.d/disable

              touch /etc/terminal-colors.d/dmesg.enable

       The following statement is recognized:

              name color-sequence

       The  name  is  a logical name of color sequence (for example "error").  The names are spe‐
       cific to the utilities.  For more details always see the COLORS section in  the  man  page
       for the utility.

       The color-sequence is a color name, ASCII color sequences or escape sequences.

   Color names
       black,  blue,  brown,  cyan, darkgray, gray, green, lightblue, lightcyan lightgray, light‐
       green, lightmagenta, lightred, magenta, red and yellow

   ANSI color sequences
       The color sequences are composed of sequences of numbers  separated  by  semicolons.   The
       most common codes are:

               0   to restore default color
               1   for brighter colors
               4   for underlined text
               5   for flashing text
              30   for black foreground
              31   for red foreground
              32   for green foreground
              33   for yellow (or brown) foreground
              34   for blue foreground
              35   for purple foreground
              36   for cyan foreground
              37   for white (or gray) foreground
              40   for black background
              41   for red background
              42   for green background
              43   for yellow (or brown) background
              44   for blue background
              45   for purple background
              46   for cyan background
              47   for white (or gray) background

   Escape sequences
       To  specify control or blank characters in the color sequences, C-style \-escaped notation
       can be used:

              \a   Bell (ASCII 7)
              \b   Backspace (ASCII 8)
              \e   Escape (ASCII 27)
              \f   Form feed (ASCII 12)
              \n   Newline (ASCII 10)
              \r   Carriage Return (ASCII 13)
              \t   Tab (ASCII 9)
              \v   Vertical Tab (ASCII 11)
              \?   Delete (ASCII 127)
              \_   Space
              \\   Backslash (\)
              \^   Caret (^)
              \#   Hash mark (#)

       Please note that escapes are necessary to enter a space, backslash, caret, or any  control
       character anywhere in the string, as well as a hash mark as the first character.

       For example, to use a red background for alert messages in the output of dmesg(1), use:

              echo 'alert 37;41' >> /etc/terminal-colors.d/dmesg.scheme


       The  terminal-colors.d  functionality  is  currently supported by all util-linux utilities
       which provides colorized output.  For more details always see the COLORS  section  in  the
       man page for the utility.

       terminal-colors.d  is  part  of  the util-linux package and is available from Linux Kernel
       Archive ⟨ftp://ftp.kernel.org/pub/linux/utils/util-linux/⟩.
