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
  -number
      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
   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
