NAME         top

       scriptreplay - play back typescripts, using timing information

SYNOPSIS         top

       scriptreplay [options] [-t] timingfile [typescript [divisor]]

DESCRIPTION         top

       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

       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         top

       -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.

           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         top

           % script --log-timing --log-out script.out
           Script started, file is script.out
           % ls
           <etc, etc>
           % exit
           Script done, file is script.out
           % scriptreplay --log-timing --log-out script.out
