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-up of 0.1 makes it go ten times slower than
the original session.
−I,
−−log−in fileFile containing script's terminal input.
−O,
−−log−out fileFile containing script's terminal output.
−B,
−−log−io fileFile containing script's terminal output and input.
−t,
−−timing fileFile containing script's timing output. This option overrides old-style arguments.
−T,
−−log−timing fileThis is an alias for −t, maintained for compatibility
with script(1)
command-line options.
−s,
−−typescript fileFile containing script's terminal
output. Deprecated alias to −−log−out. This
option overrides old-style arguments.
−c,
−−cr−mode modeSpecifies how to use the CR (0x0D, carriage return) character from log files. The default mode is auto, in this case CR is replaced with line break for stdin log, because otherwise scriptreplay would overwrite the same line. The other modes are never and always.
−d,
−−divisor numberSpeed 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. This option overrides old-style arguments.
−m,
−−maxdelay numberSet the maximum delay between updates to number of seconds. The argument is a floating-point number. This can be used to avoid long pauses in the typescript replay.
−−summaryDisplay details about the session recorded in the
specified timing file and exit. The session has to be
recorded using advanced format (see
script(1)) option
−−logging−format for
more details).
−x,
−−stream typeForces scriptreplay to print
only the specified stream. The supported stream types
are in,
out,
signal,
or info.
This option is recommended for multi-stream logs (e.g.,
−−log−io)
in order to print only specified data.
−V,
−−versionDisplay version information and exit.
−h,
−−helpDisplay help text and exit.
% script --log-timing file.tm --log-out script.out Script started, file is script.out % ls <etc, etc> % exit Script done, file is script.out % scriptreplay --log-timing file.tm --log-out script.out
The original scriptreplay program was written by Joey Hess The program was re-written in C by James Youngman and Karel Zak
The scriptreplay command is part of the util-linux package and is available from Linux Kernel Archive
