DESCRIPTION

The halt command syncs data to the disks and then stops the processor.  The
machine does not reboot.

When the halt command is finished, you will see one of the following messages.
When you do, it is safe to turn the machine off.

PS/2:       System halted, you may turn the power off now
            Type Enter to reboot :

AIX/370:    916-790 Loading a wait PSW (Use CP to re-ipl)

The halt command normally logs the shutdown using syslog and places a shutdown
record in the login accounting file /usr/adm/wtmp.  These actions are inhibited
if the -n or -q options are used.

FLAGS

-l      Do not log halt.  This flag is implied by -n and -q.
-n      Prevents the sync before stopping.
-q      Causes a quick halt, no graceful shutdown is attempted.
-y      Halts the system for a dial-up.
