NAME ^

lock -- reserves a terminal

SYNOPSYS ^

lock [-n] [-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 someone with the appropriate privileges.

OPTIONS

All of the specified options are optional.

-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.

CAVEATS ^

The BSD version of the lock command supports using an S/Key to lock the terminal.

AUTHOR ^

The Perl implementation of lock was writtem by Aron Atkins, atkins@gweep.net.
