HALT(8)                                                                HALT(8)


NAME
       halt - stop the processor

SYNOPSIS
       /etc/halt [ -n ] [ -q ] [ -y ]

DESCRIPTION
       Halt  writes out sandbagged information to the disks and then stops the
       processor.  The machine does not reboot, even if the auto-reboot switch
       is set on the console.

       The  -n option prevents the sync before stopping.  The -q option causes
       a quick halt, no graceful shutdown is  attempted.   The  -y  option  is
       needed if you are trying to halt the system from a dialup.

       Halt  normally  logs the shutdown using syslog(8) and places a shutdown
       record in the login accounting file /usr/adm/wtmp.  These  actions  are
       inhibited if the -n or -q options are present.

SEE ALSO
       reboot(8), shutdown(8), syslogd(8)

BUGS
       It is very difficult to halt a VAX, as the machine wants to then reboot
       itself.  A rather tight loop suffices.
