SHUTDOWN(8)							   SHUTDOWN(8)

NAME
       shutdown - close down the system at a given time

SYNOPSIS
       /usr/etc/shutdown  [  -k	 ] [ -r ] [ -h ] [ -n ] [ -p ] 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, saving
       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
       system.	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  terminate
       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!)

       The  -n	option	prevents  the  normal sync(2) before stopping.	The -p
       option causes the machine to be powered down if the -h option  is  also
       specified.

       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)

BUGS
       Only allows you to kill the system between now and 23:59 if you use the
       absolute time for shutdown.
