poweroff(8)

halt(8)                 System Administration Commands                 halt(8)

NAME
       halt, poweroff - stop the processor

SYNOPSIS
       /usr/sbin/halt [-dlnqy][-c comment]


       /usr/sbin/poweroff [-dlnqy][-c comment]

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(8), 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:

       -c comment    Include  the  supplied comment in any messages logged and
                     as much of the comment as will fit into the wtmpx record.
                     If a crash dump is being forced make the  comment  avail‐
                     able  in  the  crash  dump.  The  comment will need to be
                     quoted according to the shell's quoting rules.


       -d            Force  a  system  crash  dump   before   rebooting.   See
                     dumpadm(8)  for  information  on configuring system crash
                     dumps.


       -l            Suppress sending a message to the system log daemon, sys‐
                     logd(8), about who executed halt.


       -n            Prevent the sync(8) before stopping.


       -q            Quick halt. No graceful shutdown is attempted.


FILES

                         tion.

NOTES
       The  halt  and  poweroff  utilities do not cleanly shutdown smf(7) ser‐
       vices, execute the scripts in /etc/rcnum.d, or execute shutdown actions
       in inittab(5). To ensure a complete shutdown of  system  services,  use
       shutdown(8) or init(8) to reboot a Solaris system.


       System  halt may be blocked if an admin has used sysadm(8) to place the
       system into a noreboot maintenance  mode,  or  if  the  config/noreboot
       property is set to true on the svc:/system/boot-config SMF service.
