== NAME
scriptreplay - play back typescripts, using timing information
== SYNOPSIS
*scriptreplay* [options] _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 file specified by *--log-timing*.
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
*--log-out*.
If the third parameter or *--divisor* 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-down of 0.1 makes it go ten times slower than the original session.
During the replay, you can interactively speed up, slow down, or pause the
playback using the Up, Down, and Space keys.
== OPTIONS
*-I*, *--log-in* _file_::
File containing *script*'s terminal input.
*-O*, *--log-out* _file_::
File containing *script*'s terminal output.
*-B*, *--log-io* _file_::
File containing *script*'s terminal output and input.
*-t*, *--timing* _file_::
File containing *script*'s timing output.
This option replaces the _timingfile_ positional argument.
*-T*, *--log-timing* _file_::
This is an alias for *-t*, maintained for compatibility with *script*(1) command-line options.
*-s*, *--typescript* _file_::
Deprecated alias of *--log-out*.
*-c*, *--cr-mode* _mode_::
Specifies how to handle the CR (carriage return, 0x0D) character from log
files. The default mode is *auto*, in which case CR is replaced with a
line break for the stdin log, because otherwise *scriptreplay* would
overwrite the same line. The other modes are *never* and *always*.
*-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.
*--summary*::
Display details about the session recorded in the specified timing file and
exit. The session must have been recorded using the *advanced* format (see
*script*(1) option *--logging-format* for more details).
*-x*, *--stream* _type_::
Forces *scriptreplay* to print only the specified stream. The supported stream
types are *in*, *out*, *signal*, and *info*. This option is recommended for
multi-stream logs (created with *--log-io*) in order to print only the desired
data.

== EXAMPLES
....
% script --log-timing file.tm --log-out script.out
Script started, file is script.out
% ls
<etc, etc>
% exit
Script done, file is script.out
% scriptreplay --log-timing file.tm --log-out script.out
....
== KEY BINDINGS
The following keys control the playback of the script:
- *Space*: Toggles pause and unpause. Press this key to pause the playback, and press it again to resume.
- *Up Arrow*: Increases the playback speed. Each press of this key will make the script replay faster by x0.1.
- *Down Arrow*: Decreases the playback speed. Each press of this key will slow down the script replay by x0.1.
== AUTHORS
The original *scriptreplay* program was written by mailto:joey@kitenet.net[Joey Hess]. The program was re-written in C by mailto:jay@gnu.org[James Youngman] and mailto:kzak@redhat.com[Karel Zak]
