NAME

6       script - make typescript of terminal session
7

SYNOPSIS

9       script [options] [file]
10

DESCRIPTION

12       script  makes  a typescript of everything printed on your terminal.  It
13       is useful for students who need a hardcopy  record  of  an  interactive
14       session  as  proof  of  an  assignment,  as  the typescript file can be
15       printed out later with lpr(1).
16
17       If the argument file is given, script saves all dialogue in  file.   If
18       no file name is given, the typescript is saved in the file typescript.
19

OPTIONS

21       -a, --append
22              Append  the  output  to  file or typescript, retaining the prior
23              contents.
24
25       -c, --command command
26              Run the command rather than an interactive shell.  This makes it
27              easy  for  a  script  to  capture  the  output of a program that
28              behaves differently when its stdout is not a tty.
29
30       -e, --return
31              Return the exit code of the child process.  Uses the same format
32              as bash termination on signal termination exit code is 128+n.
33
34       -f, --flush
35              Flush  output  after  each write.  This is nice for telecoopera‐
36              tion: one person does `mkfifo foo; script -f foo',  and  another
37              can supervise real-time what is being done using `cat foo'.
38
39       --force
40              Allow  the default output destination, i.e. the typescript file,
41              to be a hard or symbolic link.  The command will follow  a  sym‐
42              bolic link.
43
44       -q, --quiet
45              Be quiet.
46
47       -t, --timing[=file]
48              Output  timing  data  to  standard error, or to file when given.
49              This data contains two fields, separated by a space.  The  first
50              field indicates how much time elapsed since the previous output.
51              The second field indicates how many characters were output  this
52              time.   This  information can be used to replay typescripts with
53              realistic typing and output delays.
54
55       -V, --version
56              Output version information and exit.
57
58       -h, --help
59              Output help and exit.
60

NOTES

62       The script ends when the forked shell exits (a control-D  to  exit  the
63       Bourne  shell  (sh(1)),  and exit, logout or control-d (if ignoreeof is
64       not set) for the C-shell, csh(1)).
65
66       Certain interactive commands, such as  vi(1),  create  garbage  in  the
67       typescript  file.   Script works best with commands that do not manipu‐
68       late the screen, the results are meant to emulate a hardcopy terminal.
69

ENVIRONMENT

71       The following environment variable is utilized by script:
72
73       SHELL  If the variable SHELL exists, the shell forked by script will be
74              that  shell.  If  SHELL is not set, the Bourne shell is assumed.
75              (Most shells set this variable automatically).
76

SEE ALSO

78       csh(1) (for the history mechanism), scriptreplay(1).
79

HISTORY

81       The script command appeared in 3.0BSD.
82

BUGS

84       Script places everything in  the  log  file,  including  linefeeds  and
85       backspaces.  This is not what the naive user expects.
