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
- Append the output to file or
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.
- -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 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).
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 package and is available from
ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
