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 file specified by --log-timing.
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 --log-out.
If the third parameter or --divisor 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-down of 0.1 makes it go ten times slower than the original session.
