LOCK(1)			FreeBSD	General	Commands Manual		       LOCK(1)

NAME
     lock -- reserve a terminal

SYNOPSIS
     lock [-npv] [-t timeout]

DESCRIPTION
     The lock 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.

     Options:

     -n		 Don't use a timeout value.  Terminal will be locked forever.

     -p		 A password is not requested, instead the user's current login
		 password is used.

     -t	timeout	 The time limit	(default 15 minutes) is	changed	to timeout
		 minutes.

     -v		 Disable switching virtual terminals while this	terminal is
		 locked.  This option is implemented in	a way similar to the
		 -S option of vidcontrol(1), and is only available if the ter-
		 minal in question is a	syscons(4) virtual terminal.

HISTORY
     The lock command appeared in 3.0BSD.

FreeBSD	9.3			 July 10, 2002			   FreeBSD 9.3
