NAME

6       scriptreplay - play back typescripts, using timing information
7

SYNOPSIS

9       scriptreplay [options] [-t] timingfile [typescript [divisor]]
10

DESCRIPTION

12       This program replays a typescript, using timing information to ensure
13       that output happens in the same rhythm as it originally appeared when
14       the script was recorded.
15
16       The replay simply displays the information again; the programs that
17       were run when the typescript was being recorded are not run again.
18       Since the same information is simply being displayed, scriptreplay is
19       only guaranteed to work properly if run on the same type of terminal
20       the typescript was recorded on. Otherwise, any escape characters in the
21       typescript may be interpreted differently by the terminal to which
22       scriptreplay is sending its output.
23
24       The timing information is what script(1) outputs to file specified by
25       --log-timing.
26
27       By default, the typescript to display is assumed to be named
28       typescript, but other filenames may be specified, as the second
29       parameter or with option --log-out.
30
31       If the third parameter or --divisor is specified, it is used as a
32       speed-up multiplier. For example, a speed-up of 2 makes scriptreplay go
33       twice as fast, and a speed-down of 0.1 makes it go ten times slower
34       than the original session.

OPTIONS

37       -I, --log-in file
38           File containing script's terminal input.
39
40       -O, --log-out file
41           File containing script's terminal output.
42
43       -B, --log-io file
44           File containing script's terminal output and input.
45
46       -t, --timing file
47           File containing script's timing output. This option overrides
48           old-style arguments.
49
50       -T, --log-timing file
51           This is an alias for -t, maintained for compatibility with
52           script(1) command-line options.
53
54       -s, --typescript file
55           File containing script's terminal output. Deprecated alias to
56           --log-out. This option overrides old-style arguments.
57
58       -c, --cr-mode mode
59           Specifies how to use the CR (0x0D, carriage return) character from
60           log files. The default mode is auto, in this case CR is replaced
61           with line break for stdin log, because otherwise scriptreplay would
62           overwrite the same line. The other modes are never and always.
63
64       -d, --divisor number
65           Speed up the replay displaying this number of times. The argument
66           is a floating-point number. It’s called divisor because it divides
67           the timings by this factor. This option overrides old-style
68           arguments.
69
70       -m, --maxdelay number
71           Set the maximum delay between updates to number of seconds. The
72           argument is a floating-point number. This can be used to avoid long
73           pauses in the typescript replay.
74
75       --summary
76           Display details about the session recorded in the specified timing
77           file and exit. The session has to be recorded using advanced format
78           (see script(1) option --logging-format for more details).
79
80       -x, --stream type
81           Forces scriptreplay to print only the specified stream. The
82           supported stream types are in, out, signal, or info. This option is
83           recommended for multi-stream logs (e.g., --log-io) in order to
84           print only specified data.
85
86       -h, --help
87           Display help text and exit.
88
89       -V, --version
90           Print version and exit.

EXAMPLES

93           % script --log-timing file.tm --log-out script.out
94           Script started, file is script.out
95           % ls
96           <etc, etc>
97           % exit
98           Script done, file is script.out
99           % scriptreplay --log-timing file.tm --log-out script.out
