SCRIPTLIVE(1)                 User Commands                 SCRIPTLIVE(1)

NAME         top

       scriptlive - re-run session typescripts, using timing information

SYNOPSIS         top

       scriptlive [options] timingfile typescript

DESCRIPTION         top

       This program re-runs a typescript, using stdin typescript and
       timing information to ensure that input happens in the same rhythm
       as it originally appeared when the script was recorded.

       The session is executed in a newly created pseudoterminal with the
       user’s $SHELL (or defaults to /bin/bash).

       Be careful! The typescript may contain arbitrary commands. It is
       recommended to use "scriptreplay --stream in --log-in typescript"
       (or with --log-io instead of --log-in) to verify the typescript
       before it is executed with scriptlive.

       The timing information is what script(1) outputs to the file
       specified by --log-timing. The typescript has to contain stdin
       information, and is what script(1) outputs to the file specified
       by --log-in or --log-io.

OPTIONS         top

       -I, --log-in file
           File containing script's terminal input.

       -B, --log-io file
           File containing script's terminal output and input.

       -E, --echo when
           This option controls the ECHO flag for the slave end of the
           session’s pseudoterminal. The supported modes are always,
           never, and auto.

           The default is auto — in which case ECHO is enabled. This
           default behavior is subject to change.

       -t, --timing file
           File containing script's timing output. This option replaces
           the timingfile positional argument.

       -T, --log-timing file
           An alias for -t; maintained for compatibility with the
           script(1) command-line options.

       -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.

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

       -V, --version
           Display version and exit.

EXAMPLES         top

           % script --log-timing file.tm --log-in script.in
           Script started, file is script.out
           % date
           <etc, etc>
           % exit
           Script done, file is script.out
           % scriptlive --log-timing file.tm --log-in script.in
