NAME
script - make typescript of terminal session
SYNOPSIS
script [options] [file]
DESCRIPTION
script makes a typescript of everything displayed on your terminal. It is useful for stu‐
dents who need a hardcopy record of an interactive session as proof of an assignment, as
the typescript file can be printed out later with lpr(1).
If the argument file is given, script saves the dialogue in this file. If no filename is
given, the dialogue is saved in the file typescript.
OPTIONS
-a, --append
Append the output to file or to typescript, retaining the prior contents.
-c, --command command
Run the command rather than an interactive shell. This makes it easy for a script
to capture the output of a program that behaves differently when its stdout is not
a tty.
-e, --return
Return the exit code of the child process. Uses the same format as bash termina‐
tion on signal termination exit code is 128+n.
-f, --flush
Flush output after each write. This is nice for telecooperation: one person does
`mkfifo foo; script -f foo', and another can supervise real-time what is being done
using `cat foo'.
--force
Allow the default output destination, i.e. the typescript file, to be a hard or
symbolic link. The command will follow a symbolic link.
-q, --quiet
Be quiet (do not write start and done messages to either standard output or the
typescript file).
-t, --timing[=file]
Output timing data to standard error, or to file when given. This data contains
two fields, separated by a space. The first field indicates how much time elapsed
since the previous output. The second field indicates how many characters were
output this time. This information can be used to replay typescripts with realis‐
tic typing and output delays.
-V, --version
Display version information and exit.
-h, --help
Display help text and exit.
NOTES
The script ends when the forked shell exits (a control-D for the Bourne shell (sh(1)), and
exit, logout or control-d (if ignoreeof is not set) for the C-shell, csh(1)).
Certain interactive commands, such as vi(1), create garbage in the typescript file.
script works best with commands that do not manipulate the screen, the results are meant
to emulate a hardcopy terminal.
ENVIRONMENT
The following environment variable is utilized by script:
SHELL If the variable SHELL exists, the shell forked by script will be that shell. If
SHELL is not set, the Bourne shell is assumed. (Most shells set this variable
automatically).
SEE ALSO
csh(1) (for the history mechanism), scriptreplay(1).
HISTORY
The script command appeared in 3.0BSD.
BUGS
script places everything in the log file, including linefeeds and backspaces. This is not
what the naive user expects.
AVAILABILITY
The script command is part of the util-linux package and is available from Linux Kernel
Archive ⟨ftp://ftp.kernel.org/pub/linux/utils/util-linux/⟩.
