NAME
script —
make typescript of terminal
session
SYNOPSIS
script |
[-adfpqr]
[-c
command]
[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.
Option:
-
-
- -a
- Append the output to file or
typescript, retaining the prior contents.
-
-
- -c
command
- Run the named command instead of the
shell. Useful for capturing the output of a program that behaves
differently when associated with a tty.
-
-
- -d
- When playing back a session with the -p
flag, don't sleep between records when playing back a timestamped
session.
-
-
- -f
- Flush output after each write. This is useful for watching
the script output in real time.
-
-
- -p
- Play back a session recorded with the -r
flag in real time.
-
-
- -q
- Be quiet, and don't output started and ended lines.
-
-
- -r
- Record a session with input, output, and timestamping.
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 used 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).
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.
