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, 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.
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).
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-ng package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
