scriptreplay — play back typescripts, using timing information
scriptreplay [options]
[−t] timingfile [
typescript [divisor] ]
This program replays a typescript, using timing information to ensure that output happens in the same rhythm as it originally appeared when the script was recorded.
The replay simply displays the information again; the programs that were run when the typescript was being recorded are not run again. Since the same information is simply being displayed, scriptreplay is only guaranteed to work properly if run on the same type of terminal the typescript was recorded on. Otherwise, any escape characters in the typescript may be interpreted differently by the terminal to which scriptreplay is sending its output.
The timing information is what script(1) outputs to
standard error if it is run with the −t parameter.
By default, the typescript to display is assumed to be
named typescript, but
other filenames may be specified, as the second parameter or
with option −s.
If the third parameter is specified, it is used as a speed-up multiplier. For example, a speed-up of 2 makes scriptreplay go twice as fast, and a speed-up of 0.1 makes it go ten times slower than the original session.
The first three options will override old-style arguments.
−t,
−−timing fileFile containing script's timing output.
−s,
−−typescript fileFile containing script's terminal output.
−d,
−−divisor numberSpeed 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.
−m,
−−maxdelay numberSet the maximum delay between transcript updates to number of seconds. The argument is a floating point number. This can be used to avoid long pauses in the transcript replay.
−V,
−−versionDisplay version information and exit.
−h,
−−helpDisplay help text and exit.
% script --timing=file.tm script.out Script started, file is script.out % ls <etc, etc> % exit Script done, file is script.out % scriptreplay --timing file.tm --typescript script.out
