SCRIPT

 

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 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 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 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’.

–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 realistic 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).
