9 script [[-a] [[-f] [[-q] [[-t] [[file]
10 __DESCRIPTION__
11
12
13 Script makes a typescript of everything printed on your ter-
14 minal. It is useful for students who need a hardcopy record
15 of an interactive session as proof of an assignment, as the
16 typescript file can be printed out later with
17 lpr(1).
18
19
20 If the argument file is given, script saves all dialogue in file. If no file name is given, the typescript is saved in the file typescript.
21
22
23 Options:
24 -a Append the output to file or typescript
25 , retaining the prior contents.
26
27
28 -f
29 Flush output after each write. This is nice for tele- cooperation: One person does `mkfifo foo; script -f foo' and another can supervise real-time what is being done using `cat foo'.
30
31
32 -q
33 Be quiet.
34
35
36 -t
37 Output timeing data to standard error. This data con- tains
38 two fields, separated by a space. The first field indicates
39 how much time elapsed since the pre- vious output. The
40 second field indicates how many characters were output this
41 time. This information can be used to replay typescripts
42 with realistic typ- ing and output delays.
43
44
45 The script ends when the forked shell exits (a
46 ''control-D'' to exit the Bourne shell (sh(1)),
47 and ''exit'', ''logout'' or ''control-d'' (if
48 ''ignoreeof'' is not set) for the C-shell,
49 csh(1)).
50
51
52 Certain interactive commands, such as vi(1), create
53 garbage in the typescript file. Script works best with
54 commands that do not manipulate the screen, the results are
55 meant to emulate a hardcopy terminal.

58 __ENVIRONMENT__
59
60
61 The following environment variable is utilized by
62 script:
63 SHELL
64
65
66 If the variable SHELL exists, the shell forked by
67 script will be that shell. If SHELL is not set, the
68 Bourne shell is assumed. (Most shells set this vari- able
69 automatically).

75 csh(1) (for the ''history''
76 mechanism).
77 __HISTORY__
78
79
80 The script command appeared in 3.0 BSD
81 .
82 __BUGS__
83
84
85 Script places __everything__ in the log file, including
86 line- feeds and backspaces. This is not what the naive user
87 expects.
