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 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.
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
This is an alias for -t, maintained for compatibility with script(1) command-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 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 number
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. This option
overrides old-style arguments.
-m, --maxdelay number
Set 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.
--summary
Display 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 type
Forces 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, --version
Display version information and exit.
-h, --help
Display help text and exit.
EXAMPLES
% 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
