scriptlive - re-run session typescripts, using timing information


scriptlive [options] [-t] timingfile [-I|-B] typescript


This program re-runs a typescript, using stdin typescript and timing information to ensure that input happens in the same rhythm as it originally appeared when the script was recorded.

The session is executed in a newly created pseudoterminal with the user's $SHELL (or defaults to /bin/bash).

Be careful! Do not forget that the typescript may contains arbitrary commands. It is recommended to use "scriptreplay --stream in --log-in typescript" (or with --log-io instead of --log-in to verify the typescript before it is executed by scriptlive(1).

The timing information is what script(1) outputs to file specified by --log-timing. The typescript has to contain stdin information and it is what script(1) outputs to file specified by --log-in or --log-io.


File containing script's terminal input.
File containing script's terminal output and input.
File containing script's timing output. This option overrides old-style arguments.
Aliased to -t, maintained for compatibility with script(1) command-line options.
Speed up the replay displaying this number of times. The argument is a floating-point number. It's called divisor because it divides the timings by this factor. This option overrides old-style arguments.
Set the maximum delay between updates to number of seconds. The argument is a floating-point number. This can be used to avoid long pauses in the typescript replay.
Display version information and exit.
Display help text and exit.


% script --log-timing --log-in
Script started, file is script.out
% date
