script — make typescript of terminal session

script [-a] [-c command] [-e] [-f] [-q] [-t[=file]] [-V] [-h] [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 typescript 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
Append the output to file or typescript, retaining the prior con‐

-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 termination 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'.

Allow the default output destination, i.e. the typescript file,
to be a hard or symbolic link. The command will follow a sym‐
bolic link.

-q, --quiet
Be quiet.

-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
realistic typing and output delays.

-V, --version
Output version information and exit.

-h, --help
Output help and exit.

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 type‐
script 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 automatically).

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
