NAME

scriptlive - re-run session typescripts, using timing information

SYNOPSIS

scriptlive [options] [-t] timingfile [-I|-B] typescript

DESCRIPTION

This program re-run 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 newly created pseudo terminal with user’s $SHELL (or defaults to /bin/bash).
Be careful! Do not forget that the typescript may contains 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 by scriptlive(1).
The timing information is what script(1) outputs to file specified by --log-timing. The typescript has to contain stdin information and it is what script(1) outputs to file specified by --log-in or --log-io.

OPTIONS

-I, --log-in file
File containing script’s terminal input.
-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
aliast to -t, maintained for compatibility with 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 transcript updates to number of seconds. The argument is a floating point number. This can be used to avoid long pauses in the transcript replay.
-V, --version
Display version information and exit.
-h, --help
Display help text and exit.

EXAMPLE

% 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
