NAME

scriptreplay – play back typescripts, using timing information

SYNOPSIS

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

DESCRIPTION

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 outputs to standard error if
it is run with the -t parameter.

By default, the typescript to display is assumed to be named type‐
script, but other filenames may be specified, as the second parameter
or with option -s.

If the third parameter is specified, it is used as a speed-up multi‐
plier. 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 orig‐
inal session.

OPTIONS

The first three options will override old-style arguments.

-t, –timing file
File containing script’s timing output.

-s, –typescript file
File containing script’s terminal output.

-d, –divisor number
Speed up the replay displaying this number of times. The argu‐
ment is a floating point number. It’s called divisor because it
divides the timings by this factor.

-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 –timing=file.tm script.out
Script started, file is script.out
% ls

% exit
Script done, file is script.out
% scriptreplay –timing file.tm –typescript script.out
