scriptlive − re−run session typescripts, using timing information
SYNOPSIS
scriptlive [options] timingfile typescript
DESCRIPTION
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
−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
% 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
