NAME

       scriptreplay - play back typescripts, using timing information

SYNOPSIS

       scriptreplay [options] 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.

       During the replay, you can interactively speed up, slow down, or pause the playback using the Up, Down,
       and Space keys.

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 replaces the timingfile positional argument.

       -T, --log-timing file
           This is an alias for -t, maintained for compatibility with script(1) command-line options.

       -s, --typescript file
           Deprecated alias of --log-out.

       -c, --cr-mode mode
           Specifies how to handle the CR (carriage return, 0x0D) character from log files. The default mode is
           auto, in which case CR is replaced with a line break for the 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 must
           have been recorded using the 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, and info. This option is recommended for multi-stream logs (created with --log-io) in order
           to print only the desired data.

       -h, --help
           Display help text and exit.

       -V, --version
           Display 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

KEY BINDINGS

       The following keys control the playback of the script:

       •   Space: Toggles pause and unpause. Press this key to pause the playback, and press it again to resume.

       •   Up Arrow: Increases the playback speed. Each press of this key will make the script replay faster by
           x0.1.

       •   Down Arrow: Decreases the playback speed. Each press of this key will slow down the script replay by
           x0.1.
