.Sh DESCRIPTION
|
|
.Nm 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
|
|
.Xr lpr 1 .
|
|
.Pp
|
|
If the argument
|
|
.Ar file
|
|
is given,
|
|
.Nm
|
|
saves all dialogue in
|
|
.Ar file .
|
|
If no file name is given, the typescript is saved in the file
|
|
.Pa typescript .
|
|
.Pp
|
|
If the argument
|
|
.Ar command ...
|
|
is given,
|
|
.Nm
|
|
will run the specified command with an optional argument vector
|
|
instead of an interactive shell.
|
|
.Pp
|
|
Options:
|
|
.Bl -tag -width xxxxxxx
|
|
.It Fl a
|
|
Append the output to
|
|
.Ar file
|
|
or
|
|
.Pa typescript ,
|
|
retaining the prior contents.
|
|
.It Fl k
|
|
Log keys sent to program as well as output.
|
|
.It Fl q
|
|
Run in quiet mode, omit the start and stop status messages.
|
|
.It Fl t Ar time
|
|
Specify time interval between flushing script output file. A value of 0
|
|
causes
|
|
.Nm
|
|
to flush for every character I/O event. The default interval is
|
|
30 seconds.
|
|
.El
|
|
.Pp
|
|
The script ends when the forked shell (or command) exits (a
|
|
.Em control-D
|
|
to exit
|
|
the Bourne shell
|
|
.Pf ( Xr sh 1 ) ,
|
|
and
|
|
.Em exit ,
|
|
.Em logout
|
|
or
|
|
.Em control-d
|
|
(if
|
|
.Em ignoreeof
|
|
is not set) for the
|
|
C-shell,
|
|
.Xr csh 1 ) .
|
|
.Pp
|
|
Certain interactive commands, such as
|
|
.Xr vi 1 ,
|
|
create garbage in the typescript file.
|
|
.Nm Script
|
|
works best with commands that do not manipulate the screen.
|
|
The results are meant to emulate a hardcopy terminal, not an addressable one.
|
|
.Sh ENVIRONMENT
|
|
The following environment variable is utilized by
|
|
.Nm script :
|
|
.Bl -tag -width SHELL
|
|
.It Ev SHELL
|
|
If the variable
|
|
.Ev SHELL
|
|
exists, the shell forked by
|
|
.Nm
|
|
will be that shell.
|
|
If
|
|
.Ev SHELL
|
|
is not set, the Bourne shell
|
|
is assumed.
|
|
(Most shells set this variable automatically).
|
|
.El
|
|
.Sh SEE ALSO
|
|
.Xr csh 1
|
|
(for the
|
|
.Em history
|
|
mechanism).
|
|
.Sh HISTORY
|
|
The
|
|
.Nm
|
|
command appeared in
|
|
.Bx 3.0 .
|
|
.Sh BUGS
|
|
.Nm Script
|
|
places
|
|
.Sy everything
|
|
in the log file, including linefeeds and backspaces.
|
|
This is not what the naive user expects.
|
|
.Pp
|
|
It is not possible to specify a command without also naming the script file
|
|
because of argument parsing compatibility issues.
|
|
.Pp
|
|
When running in
|
|
.Fl k
|
|
mode, echo cancelling is far from ideal. The slave terminal mode is checked
|
|
for ECHO mode to check when to avoid manual echo logging. This does not
|
|
work when in a raw mode where the program being run is doing manual echo.
