NAME
       shutdown - bring the system down

SYNOPSIS
       shutdown [OPTION]... TIME [MESSAGE]

DESCRIPTION
       shutdown arranges for the system to be brought down in a safe way.  All
       logged-in users are notified that the system is going down and,	within
       the last five minutes of TIME, new logins are prevented.

       TIME  may  have	different  formats, the most common is simply the word
       'now' which will bring the system down immediately.  Other  valid  for-
       mats  are  +m,  where m is the number of minutes to wait until shutting
       down and hh:mm which specifies the time on the 24hr clock.

       Once TIME has elapsed, shutdown sends a request to the  init(8)	daemon
       to bring the system down into the appropriate runlevel.

OPTIONS
       -r     Requests	that  the system be rebooted after it has been brought
	      down.

       -h     Requests that the system be either halted or powered  off  after
	      it has been brought down, with the choice as to which left up to
	      the system.

       -H     Requests that the system be halted after	it  has  been  brought
	      down.

       -P     Requests	that  the  system  be  powered	off  after it has been
	      brought down.

       -c     Cancels a running shutdown.  TIME is  not  specified  with  this
	      option, the first argument is MESSAGE.

       -k     Only  send  out  the warning messages and disable logins, do not
	      actually bring the system down.

NOTES
       This tool is provided for compatibility with the traditional  System  V
       init(8).   Upstart  has	no  notion  of	runlevels itself, this and the
       telinit(8) tool are provided to emulate their behaviour.

       When invoked it generates a runlevel event, with an argument containing
       the new runlevel.
