poweroff(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 informa-
tion 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 Halt the system, even from a dialup terminal.

NOTES
The halt and poweroff utilities do not 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.
