.Sh SYNOPSIS
|
|
.Nm

|
.Op Fl npv
|
|
.Op Fl t Ar timeout
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility requests a password from the user, reads it again for verification
|
|
and then will normally not relinquish the terminal until the password is
|
|
repeated.
|
|
There are two other conditions under which it will terminate: it
|
|
will timeout after some interval of time and it may be killed by someone
|
|
with the appropriate permission.
|
|
.Pp
|
|
The following options are available:
|
|
.Bl -tag -width indent
|
|
.It Fl n
|
|
Do not use a timeout value.
|
|
Terminal will be locked forever.
|
|
.It Fl p
|
|
A password is not requested, instead the user's current login password
|
|
is used.
|
|
.It Fl t Ar timeout
|
|
The time limit (default 15 minutes) is changed to
|
|
.Ar timeout
|
|
minutes.
|
|
.It Fl v
|
|
Disable switching virtual terminals while this terminal is locked.
|
|
This option is implemented in a way similar to the
|
|
.Fl S
|
|
option of
|
|
.Xr vidcontrol 1 ,
|
|
and thus has the same restrictions.
|
|
It is only available if the terminal in question is a
|
|
.Xr syscons 4
|
|
virtual terminal.
