script -- make typescript of terminal session
script [-a] [-c COMMAND] [-e] [-f] [-q] [-t] [file]
Script makes a typescript of everything printed on your terminal. It is useful for students
who need a hardcopy record of an interactive session as proof of an assignment, as the type-
script file can be printed out later with lpr(1) .
If the argument file is given, script saves all dialogue in file. If no file name is given,
the typescript is saved in the file typescript.
-a Append the output to file or typescript, retaining the prior contents.
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
-e Return the exit code of the child process. Uses the same format as bash termination
on signal termination exit code is 128+n.
-f 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'.
-q Be quiet.
-t Output timing data to standard error. 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 informa-
tion can be used to replay typescripts with realistic typing and output delays.
The script ends when the forked shell exits (a control-D to exit 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.
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 automati-
csh(1) (for the history mechanism), scriptreplay(1) .
The script command appeared in 3.0BSD.
Script places everything in the log file, including linefeeds and backspaces. This is not
what the naive user expects.
The script command is part of the util-linux package and is available from ftp://ftp.ker-
