NAME

leave - remind you when you have to leave

SYNOPSIS

leave [ hhmm ]

DESCRIPTION

The leave command waits until the speci®ed time, then reminds you to leave. You are reminded 5 minutes and 1 minute before the actual time, at the time, and every minute thereafter. When you log off, leave exits.

The time of day is in the form hhmm, where hh is a time in hours (which can range from 0 through 11 or 0 through 24 hours), and mm is the number of minutes after the speci®ed hour. If the value of hh is greater than 11 (24-hour clock time), the speci®ed value is reduced by 12 to a new value in the range of 0 through 11, thus ensuring that the alarm time is always set to activate within the next 12 hours. For example, if hhmm is 1350 and the current time is 4:00 PM (1600), the 1350 value is changed to 150 and the alarm is set for 1:50 AM, nine hours and 50 minutes later. On the other hand, if it is 9:00 AM and hhmm is speci®ed as 2200 (10:00 PM), the value used is converted to 1000 and the alarm is set for one hour later instead of 13 hours as speci®ed.

If no argument is provided, leave prompts with

When do you have to leave?

A reply of newline causes leave to exit; otherwise the reply is assumed to be a time. This form is suitable for inclusion in a .login or .profile ®le.

The leave command ignores interrupts, quits, and terminate signals. To get rid of it you should either log off or use kill -9giving its process ID.

EXAMPLES

The command

leave 1204

sends an alarm (a beep) to your terminal to remind you that you have to leave at 12:04 and reminds you that you are late at one minute intervals after 12:04.

WARNINGS

The leave command checks to see if a user has logged out by checking the /etc/utmp ®le every 100 seconds. If a user logs out and logs back in to the same tty before leave makes its periodic check, leave may not know that the user has logged out.
