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.

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

HISTORY
     The lock command appeared in 3.0BSD.
