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 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.
% 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
