lock(1) General Commands Manual lock(1)
NAME
lock - Requests and verifies a user password
SYNOPSIS
lock [-number]
The lock command requests and reads a password from a user, then requests the password a second time to verify it.
OPTIONS
Sets the time-out period to number minutes. The default value is 15 minutes.
DESCRIPTION
The lock command then locks the terminal and does not relinquish it until the password is received again, unless one of the following
occurs: The root password is entered. The time-out interval is exceeded. The command is killed by a user with appropriate permission.
The time-out default value is 15 minutes, but this can be changed with the -number option.
EXAMPLES
To lock a terminal, enter: lock
The password is requested twice, with two different prompts, so the system can verify it. If the password is not repeated within 15
minutes, the command times out. To lock a terminal for 10 minutes instead of 15, enter: lock -10
