scriptreplay - play back typescripts, using timing information
This program replays a typescript, using timing information to ensure that
output happens in the same rhythm as it originally appeared when the script
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,
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
is sending its output.
The timing information is what

run with the
By default, the typescript to display is assumed to be named
but other filenames may be specified, as the second parameter or with option
If the third parameter is specified, it is used as a speed-up multiplier.
For example, a speed-up of 2 makes
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 file
File containing script's timing output.
- -s, --typescript file
File containing script's terminal output.
- -d, --divisor number
Speed up the replay displaying this
of times. The argument is a floating point number. It's called divisor
because it divides the timings by this factor.
- -m, --maxdelay number
Set the maximum delay between transcript updates to
of seconds. The argument is a floating point number. This can be used to
avoid long pauses in the transcript replay.
- -V, --version
Display version information and exit.
- -h, --help
Display help text and exit.
