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
