shutdown		"-Kill" is the default and merely puts UNIX into 
shutdown		single-user mode.  "-Halt" halt's the system.  
shutdown		"-Reboot" reboots UNIX.  "-Fake" merely `fake's 
shutdown		a shutdown, but does not actually bring UNIX down.
shutdown	
shutdown	    -LocalMessages | -NoLocalMessages
shutdown	
shutdown		If ``-LocalMessages'' is specified (the default), a

shutdown	    -RemoteMessages | -NoRemoteMessages
shutdown	
shutdown		This option can be used on UNIX systems which have RPC.

shutdown	
shutdown	    -Fastboot | -No-Sync
shutdown	
shutdown		If ``-Fastboot'' is specified, then a fastboot(8)

shutdown	
shutdown	
shutdown	"down-time" and "up-time" should be in one of the follow forms:
shutdown	
shutdown	    HH:MM [ MM/DD [ /YY ] ]
shutdown	
shutdown		where "HH" is an hour (24 hour clock) and "MM" are 
shutdown		minutes.  You may optionally supply a date (today's 
shutdown		date is the default) consisting of a month ("MM"), 
shutdown		a day of the month ("DD"), and an optional year
