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 overide 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
