lock(1) BSD General Commands Manual lock(1)
NAME
lock -- reserve a terminal
SYNOPSIS
lock [-p] [-t timeout]
DESCRIPTION
lock 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 some-
one with the appropriate permission.
Options:
-p A password is not requested, instead the user's current login
password is used. If the user has an S/Key key, they may
also use it to unlock the terminal. To do this the user
should enter "s/key" at the unlock "Key:" prompt. The user
will then be issued an S/Key challenge to which they may
respond with a six-word S/Key one-time password.
-t timeout The time limit (default 15 minutes) is changed to timeout
minutes.
