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
at the same speed 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 type-
script may be interpreted differently by the terminal to which scriptreplay is sending its
The timing information is what script(1) outputs to standard error if it is run with the
By default, the typescript to display is assumed to be named typescript, but other file-
names 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 overide old-style arguments.
-t, --timing file
File containing script timing output.
-s, --typescript file
File containing the script terminal output.
-d, --divisor number
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.
