NAME
script
—
make typescript of terminal
session
SYNOPSIS
script |
[-a ] [-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.
The options are as follows:
-a
- Append the output to file or typescript, retaining the prior contents.
-c
command- Run
sh
-c
command, instead of an interactive shell. To run a command with arguments, enclose both in quotes.
The script ends when the forked program exits (an
exit
, logout
, or control-D
(‘^D
’) will exit most interactive
shells). script
will exit with the status of 0
unless any of its child processes fail, in which case,
script
will return 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
SHELL
- Name of the shell to be forked by
script
. If not set, the Bourne shell is assumed. (Most shells set this variable automatically.)
EXAMPLES
Start a virtual machine and log all console output to a file:
$ script -c "vmctl start -c myvm" myvm.typescript

BUGS
script
places
everything
in the log file, including linefeeds and backspaces. This is not what the
naive user expects.
