|
.Sh DESCRIPTION
|
|
.Nm
|
|
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
|
|
Option:
|
|
.Bl -tag -width Ds
|
|
.It Fl a

.It Fl c Ar command
|
|
Run the named
|
|
.Ar command
|
|
instead of the shell.
|
|
Useful for capturing the output of a program that behaves differently when
|
|
associated with a tty.
|
|
.It Fl d
|
|
When playing back a session with the
|
|
.Fl p
|
|
flag, don't sleep between records when playing back a timestamped session.
|
|
.It Fl f
|
|
Flush output after each write.
|
|
This is useful for watching the script output in real time.
|
|
.It Fl p

|
Play back a session recorded with the
|
|
.Fl r
|
|
flag in real time.
|
|
.It Fl q

|

.Pp
|
|
The script ends when the forked shell 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
|
|
works best with commands that do not manipulate the
|
|
screen, the results are meant to emulate a hardcopy
|
|
terminal.
|
|
.Sh ENVIRONMENT
|
|
The following environment variable is used by
|
|
.Nm :
|
|
.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).
