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 output.

       The timing information is what script(1) outputs to file specified by

       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.

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.

       -V, --version
              Display version information and exit.

       -h, --help
              Display help text 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
