scriptreplay — play back typescripts, using timing information
scriptreplay 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 typescript may be interpreted differently by the terminal to which scriptreplay is sending its output.
The timings 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.
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.
% script -t 2> timingfile Script started, file is typescript % ls <etc, etc> % exit Script done, file is typescript % scriptreplay timingfile
The original scriptreplay program was written by Joey Hess <[email protected]>. The program was re-written in C by James Youngman <[email protected]> and Karel Zak <[email protected]>.
The scriptreplay command is part of the util-linux-ng package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
