That's something that NUT will do for you, provided you give it the right
SHUTDOWNCMD and your UPS has enough stamina to keep your PC running for
the duration of the shutdown sequence.

> how to be sure the pc will shut down?

You mean poweroff? That will be handled by the sending the UPS a command
to shutdown in the halt sequence.

> may will get some right access problem....

We can't do anything about that, that's your job to get it right.

In essence, if you're worried this doesn't work (and you should be), the
only way to be sure is to try it out. Power your PC directly from the
mains and load the UPS with a lightbulb of about 100 Watt. Pull the plug
on your UPS and wait. If your PC shuts down before the lamp goes out,
you're fine. If not, upssched is your friend and you need a timed shutdown
after the mains is lost.
