shutdown

Hi,

We observed that after “shutdown -b” command, QNX computer informs the
user that the system can be powere off. We want the system to shutdown
(power OFF) automatically with a shutdown command. How to achieve this? Do
we require any specific feature/function for the computer hardware in
addition to ATX power supply?

Thanks,
Krupa

I don’t think QNX4 supports any sort of hardware shutdown – that is, it
will do a reboot, but it won’t do a software-triggered power down.

Only on one of our machines, shutdown -f leads to power OFF condition. With
shutdown -b system informs the user that the machine may be powered OFF.
Why does shutdown -f turn our machine OFF?

Thanks,

Take a look at the docs for Proc32 option -b for details on how to change
reboot behaviour.

shutdown -b will never reboot a system, as the shutdown code just spin after
slaying everyone else off. Shutdown -f will ask Proc to reboot via one of
the reboot methods (as mentioned above).

Will the OS respond to a 4-finger roboot after “shutdown -b”?
