NAME
      halt, poweroff - stop the processor
 


SYNOPSIS
      /usr/sbin/halt [ -dlnqy ]
 
      /usr/sbin/poweroff [ -dlnqy ]
 


DESCRIPTION
      The halt and poweroff utilities write any  pending  informa-
      tion  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.
 


OPTIONS
      The following options are supported:
 
      -d    Force  a  system  crash  dump  before  rebooting.  See
            dumpadm(1M)  for  information  on  configuring  system
            crash dumps.
 
      -l    Suppress sending a message to the system  log  daemon,
            syslogd(1M), about who executed halt.
 
      -n    Prevent the sync(1M) before stopping.
 
      -q    Quick halt. No graceful shutdown is attempted.
 
      -y    Halt the system, even from a dialup terminal.

NOTES
      The halt utility does not execute  the  rc0  scripts  as  do
      shutdown(1M) and init(1M).
 
      The poweroff utility is equivalent to init5.
