SCRIPTREPLAY(1)                  User Commands                 SCRIPTREPLAY(1)

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
