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-down 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.
-h, --help
Display help text and exit.
-V, --version
Print version 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
