HALT(1M)							      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 has 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
	     This option is ignored for backwards compatibility.

FILES
       /var/adm/wtmpx
			 History of user access	 and  administration  informa‐
			 tion.

SEE ALSO
       dumpadm(1M), init(1M), reboot(1M), shutdown(1M), sync(1M), syslogd(1M),
       inittab(4), attributes(5), smf(5)

NOTES
       The halt and poweroff utilities do not  cleanly	shutdown  smf(5)  ser‐
       vices.  Execute the scripts in /etc/rcnum.d or execute shutdown actions
       in inittab(4). To ensure a complete shutdown of	system	services,  use
       shutdown(1M) or init(1M) to reboot a Solaris system.
