Can you describe what you are trying to do?

NOTIFYCMD can be a script that you write, or /path/to/upssched.

upssched can also call out to another script.

The difference is that NOTIFYCMD gets called on every event selected by the configuration options in upsmon.conf. If you hooked this up to a text messaging gateway (triggering on OB/OL status), you would probably get several attempted text messages every time the power flickered.

CMDSCRIPT gets called when timers configured in upssched.conf have expired. This lets you debounce the signals, or shut off a system after N minutes on battery (regardless of the "low battery" status).

Source is here:


You could file an enhancement request with Debian/Ubuntu if they don't include it in any of the packages, but it's really a simple template.
