NAME¶
script
— make
typescript of terminal session
SYNOPSIS¶
script |
[-a ] [-c
COMMAND] [-f ]
[-q ] [-t ]
[file] |
DESCRIPTION¶
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.
Options:
-a
- Append the output to file or typescript, retaining the prior contents.
-c
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.
-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 information 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.
ENVIRONMENT¶
The following environment variable is utilized by
script
:
SHELL
- If the variable
SHELL
exists, the shell forked byscript
will be that shell. IfSHELL
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-ng package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
