NAME
script
- make typescript of terminal session
SYNOPSIS
script
[-a
]
[-c COMMAND
]
[-f
]
[-q
]
[-t
]
[file
]
DESCRIPTION
Script
makes a typescript of everything printed on your terminal.
It is useful for students who need a hardcopy record of an interactive
session as proof of an assignment, as the typescript file
can be printed out later with
lpr(1).
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
Options:
- -a
-
Append the output to
file
or
typescript
retaining the prior contents.
- -c COMMAND
-
Run the COMMAND rather than an interactive shell.
This makes it easy for a script to capture the output of a program that
behaves differently when its stdout is not a tty.
- -f
-
Flush output after each write. This is nice for telecooperation:
One person does `mkfifo foo; script -f foo' and another can
supervise real-time what is being done using `cat foo'.
- -q
-
Be quiet.
- -t
-
Output timing data to standard error. This data contains two fields,
separated by a space. The first field indicates how much time elapsed since
the previous output. The second field indicates how many characters were
output this time. This information can be used to replay typescripts with
realistic typing and output delays.
The script ends when the forked shell exits (a
control-D
to exit
the Bourne shell
( sh(1))
and
exit ,
logout
or
control-d
(if
ignoreeof
is not set) for the
C-shell,
csh(1)).
Certain interactive commands, such as
vi(1),
create garbage in the typescript file.
Script
works best with commands that do not manipulate the
screen, the results are meant to emulate a hardcopy
terminal.
ENVIRONMENT
The following environment variable is utilized by
script
- SHELL
-
If the variable
SHELL
exists, the shell forked by
script
will be that shell. If
SHELL
is not set, the Bourne shell
is assumed. (Most shells set this variable automatically).
SEE ALSO
csh(1)
(for the
history
mechanism),
scriptreplay(1).
HISTORY
The
script
command appeared in
BSD 3.0
BUGS
Script
places
everything
in the log file, including linefeeds and backspaces.
This is not what the naive user expects.
