       shutdown - bring the system down


       shutdown [OPTION]... TIME [MESSAGE]


       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
       formats 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.


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

       -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

       -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.


       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.
