halt(8)
NAME
halt − stop the processor
SYNTAX
/etc/halt [ −n ] [ −q ] [ −y ]
DESCRIPTION
The halt 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.
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.
RESTRICTIONS
It is very difficult to halt a VAX, as the machine wants to then reboot itself. A rather tight loop suffices.
