4 script — make typescript of terminal session
5
7 script [-a] [-c COMMAND] [-f] [-q] [-t] [file]
8
10 Script makes a typescript of everything printed on your terminal. It is
11 useful for students who need a hardcopy record of an interactive session
12 as proof of an assignment, as the typescript file can be printed out
13 later with lpr(1).
14
15 If the argument file is given, script saves all dialogue in file. If no
16 file name is given, the typescript is saved in the file typescript.
17
18 Options:
19
20 -a Append the output to file or typescript, retaining the prior con‐
21 tents.
22
23 -c COMMAND
24 Run the COMMAND rather than an interactive shell. This makes it
25 easy for a script to capture the output of a program that behaves
26 differently when its stdout is not a tty.
27
28 -f Flush output after each write. This is nice for telecooperation:
29 One person does `mkfifo foo; script -f foo' and another can
30 supervise real-time what is being done using `cat foo'.
31
32 -q Be quiet.
33
34 -t Output timing data to standard error. This data contains two
35 fields, separated by a space. The first field indicates how much
36 time elapsed since the previous output. The second field indi‐
37 cates how many characters were output this time. This information
38 can be used to replay typescripts with realistic typing and out‐
39 put delays.
40
41 The script ends when the forked shell exits (a control-D to exit the
42 Bourne shell (sh(1)), and exit, logout or control-d (if ignoreeof is not
43 set) for the C-shell, csh(1)).
44
45 Certain interactive commands, such as vi(1), create garbage in the type‐
46 script file. Script works best with commands that do not manipulate the
47 screen, the results are meant to emulate a hardcopy terminal.
48
50 The following environment variable is utilized by script:
51
52 SHELL If the variable SHELL exists, the shell forked by script will be
53 that shell. If SHELL is not set, the Bourne shell is assumed.
54 (Most shells set this variable automatically).
55
57 csh(1) (for the history mechanism), scriptreplay(1).
58
60 The script command appeared in 3.0BSD.
61
63 Script places everything in the log file, including linefeeds and
64 backspaces. This is not what the naive user expects.
65
67 The script command is part of the util-linux-ng package and is available
68 from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
