SCRIPT(1) BSD General Commands Manual SCRIPT(1)NAMEscript — make typescript of terminal session
SYNOPSISscript [-a] [-k] [-q] [-t time] [file [command ...]]
The script utility makes a typescript of everything printed on your ter‐
minal. It is useful for students who need a hardcopy record of an inter‐
active 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.
If the argument command ... is given, script will run the specified com‐
mand with an optional argument vector instead of an interactive shell.
-a Append the output to file or typescript, retaining the prior
-k Log keys sent to program as well as output.
-q Run in quiet mode, omit the start and stop status messages.
-t time Specify time interval between flushing script output file. A
value of 0 causes script to flush for every character I/O event.
The default interval is 30 seconds.
The script ends when the forked shell (or command) 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 type‐
script file. The script utility works best with commands that do not
manipulate the screen. The results are meant to emulate a hardcopy ter‐
minal, not an addressable one.
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 ALSOcsh(1) (for the history mechanism).
The script command appeared in 3.0BSD.
The script utility places everything in the log file, including linefeeds
and backspaces. This is not what the naive user expects.
It is not possible to specify a command without also naming the script
file because of argument parsing compatibility issues.
When running in -k mode, echo cancelling is far from ideal. The slave
terminal mode is checked for ECHO mode to check when to avoid manual echo
logging. This does not work when in a raw mode where the program being
run is doing manual echo.
