halt(1M)		System Administration Commands		      halt(1M)

NAME
       halt, poweroff -	stop the processor

SYNOPSIS
       /usr/sbin/halt [-dlnqy]

       /usr/sbin/poweroff [-dlnqy]

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  lo-
       gin  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,	  sys-
	     logd(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.

FILES
       /var/adm/wtmpx
	     History of	user access and	administration information.

ATTRIBUTES
       See attributes(5) for descriptions of the following attributes:

SEE ALSO
       dumpadm(1M), init(1M), reboot(1M), shutdown(1M),	sync(1M), syslogd(1M),
       attributes(5)

NOTES
       The halt	utility	does not execute the scripts in	/etc/rc_num_.d or exe-
       cute shutdown actions in	inittab(4).  To	ensure a complete shutdown  of
       system  services, use shutdown(1M) or init(1M) to reboot	a Solaris sys-
       tem.

       The poweroff utility is equivalent to init 5.
