halt(8)halt(8)Namehalt - stop the processor
/etc/halt [ -n ] [ -q ] [ -y ]
The command 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.
Options-n Prevents the sync before stopping.
-q Causes a quick halt, no graceful shutdown is attempted.
-y Halts the system from a dialup.
It is very difficult to halt a VAX, as the machine wants to then reboot
itself. A rather tight loop suffices.
