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. 

FLAGS

-numberSets 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 flag. 

EXAMPLES

     1.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.

     2.To lock a terminal for 10 minutes instead of 15, enter:

lock -10
