LEAVE(1)						      General Commands Manual							  LEAVE(1)

NAME
leave - remind you when you have to leave SYNOPSIS
leave [ [+]hhmm ] DESCRIPTION
Leave 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 time of day is in the form hhmm where hh is a time in hours (on a 12 or 24 hour clock). All times are converted to a 12 hour clock, and assumed to be in the next 12 hours. If the time is preceeded 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. Leave ignores interrupts, quits, and terminates. To get rid of it you should either log off or use ``kill -9'' giving its process id.

SHUTDOWN(8)						      System Manager's Manual						       SHUTDOWN(8)

NAME
shutdown - close down the system at a given time SYNOPSIS
shutdown [ -k ] [ -r ] [ -h ] [ -f ] [ -n ] time [ warning-message ... ] DESCRIPTION
Shutdown provides an automated shutdown procedure which a super-user can use to notify users nicely when the system is shutting down, sav- ing them from system administrators, hackers, and gurus, who would otherwise not bother with niceties. Time is the time at which shutdown will bring the system down and may be the word now (indicating an immediate shutdown) or specify a future time in one of two formats: +number and hour:min. The first form brings the system down in number minutes and the second brings the system down at the time of day indicated (as a 24-hour clock). At intervals which get closer together as apocalypse approaches, warning messages are displayed at the terminals of all users on the sys- tem. Five minutes before shutdown, or immediately if shutdown is in less than 5 minutes, logins are disabled by creating /etc/nologin and writing a message there. If this file exists when a user attempts to log in, login(1) prints its contents and exits. The file is removed just before shutdown exits. At shutdown time a message is written in the system log, containing the time of shutdown, who ran shutdown and the reason. Then a termi- nate signal is sent to init to bring the system down to single-user state. Alternatively, if -r, -h, or -k was used, then shutdown will exec reboot(8), halt(8), or avoid shutting the system down (respectively). (If it isn't obvious, -k is to make people think the system is going down!) With the -f option, shutdown arranges, in the manner of fastboot(8), that when the system is rebooted the file systems will not be checked. The -n option prevents the normal sync(2) before stopping. The time of the shutdown and the warning message are placed in /etc/nologin and should be used to inform the users about when the system will be back up and why it is going down (or anything else). FILES
/etc/nologin tells login not to let anyone log in SEE ALSO
login(1), reboot(8), fastboot(8) BUGS
Only allows you to kill the system between now and 23:59 if you use the absolute time for shutdown. 4th Berkeley Distribution November 16, 1996 SHUTDOWN(8)
