| 22 | .SH DESCRIPTION | |
| 23 | .I Halt | |
| 24 | writes out sandbagged information to the disks and then stops | |
| 25 | the processor. The machine does not reboot, even if the auto-reboot | |
| 26 | switch is set on the console. | |
| 27 | .PP | |
| 28 | The | |
| 29 | .B \-n | |
| 30 | option prevents the sync before stopping. The | |
| 31 | .B \-q | |
| 32 | option causes a quick halt, no graceful shutdown is attempted. The | |
| 33 | .B \-y | |
| 34 | option is needed if you are trying to halt the system from a dialup. | |
| 35 | .SH SEE ALSO | |
| 36 | reboot(8), shutdown(8) | |
| 37 | .SH BUGS | |
| 38 | It is very difficult to halt a VAX, as the machine wants to then | |
| 39 | reboot itself. A rather tight loop suffices. |
