scriptreplay

play back typescripts, using timing information

TLDR

Replay a typescript at the speed it was recorded

>_ scriptreplay [path/to/timing_file] [path/to/typescript]
copy

Replay a typescript at double the original speed

>_ scriptreplay [path/to/timingfile] [path/to/typescript] 2
copy

Replay a typescript at half the original speed

>_ scriptreplay [path/to/timingfile] [path/to/typescript] 0.5
copy

SYNOPSIS

scriptreplay [options] [-t] timingfile [typescript [divisor]]

OPTIONS

The first three options will override old-style arguments.

-t,--timingfile File containing script 'stiming output.

-s,--typescriptfile File containing script 'sterminal output.

-d,--divisornumber 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.

-m,--maxdelaynumber Set 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,--version Display version information and exit.

-h,--help Display help text and exit.

EXAMPLE

% 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

AVAILABILITY

The scriptreplay command is part of the util-linux package and is available from https:// www.kernel.org /pub /linux /utils /util-linux/ Linux Kernel Archive .

DESCRIPTION

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.
