LEAVE(1)                     General Commands Manual                    LEAVE(1)

     leave – remind you when you have to leave

     leave [[+]hhmm]

     The leave utility waits until the specified time, then reminds you that you
     have 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 just before it would have printed the next message.

     The following options are available:

     hhmm    The time of day is in the form hhmm where hh is a time in hours (on
             a 12 or 24 hour clock), and mm are minutes.  All times are
             converted to a 12 hour clock, and assumed to be in the next 12

     +       If the time is preceded by ‘+’, the alarm will go off in hours and
             minutes from the current time.

     If no argument is given, 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.

     To get rid of leave you should either log off or use ‘kill -s KILL’ giving
     its process id.


     The leave command appeared in 3.0BSD.
