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(1)
outputs to standard error if it is
run with the
-t
parameter.
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
-s.
If the third parameter 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
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 argument 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
<etc, etc>
% exit
Script done, file is script.out
% scriptreplay --timing file.tm --typescript script.out
