NAME
scriptreplay - play back typescripts, using timing information
SYNOPSIS
scriptreplay [options] [-t] timingfile [typescript [divisor]]
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 file specified by
--log-timing.
By default, the typescript to display is assumed to be named type-
script, 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.
OPTIONS
-I, --log-in file
File containing script's terminal input.
-O, --log-out file
File containing script's terminal output.
-B, --log-io file
File containing script's terminal output and input.
-t, --timing file
File containing script's timing output. This option overrides
old-style arguments.
-T, --log-timing file
aliast to -t, maintained for compatibility with script (1) com-
mand line options.
-s, --typescript file
File containing script's terminal output. Deprecated alias to
--log-out. This option overrides old-style arguments.
-c, --cr-mode mode
Specifies how to use CR (0x0D, carriage return) character from
log files. The default mode is auto, in this case CR is re-
placed with line break for stdin log, because otherwise scrip-
treplay will overwrite the same line. The another modes are
never and always.
-d, --divisor number
Speed up the replay displaying this number of times. The argu-
ment 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 number
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.
--summary
Display details about session recorded in the specified timing
file and exit. The session has to be recorded by advanced for-
mat (see script(1)) option --logging-format for more details).
-x, --stream type
Forces scriptreplay to print only specified stream. The sup-
ported stream types are in, out, signal, or info. This option
is recommended for multi-stream logs (e.g., --log-io) to print
only specified data.
-V, --version
Display version information and exit.
-h, --help
Display help text and exit.
EXAMPLE
% 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
