leave(1)
NAME
leave − remind you when you have to leave
SYNOPSIS
leave [hhmm]
DESCRIPTION
leave waits until the specified 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 specified hour. If the value of hh is greater than 11 (24-hour clock time), the specified 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 specifed 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 specified.
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 file.
leave ignores interrupts, quits, and terminate signals. To get rid of it you should either log off or use kill -9 giving 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
leave checks to see if a user has logged out by checking the /etc/utmp file every 100 seconds. If a user logs out and logs back in to the same tty before leave makes its periodic check, leave might not know that the user has logged out.
