UPS Service - What is the default shutdown command

shoulders · August 18, 2024, 4:21pm

In the UPS service you have the option of putting a custom shutdown command, however the tool tip says there is a defautl shutdown command, does anyone know what this command is?

When battery power is low or the shutdown timer ends, enter the custom command to overrule the default shutdown command.

Thanks

I have /sbin/poweroff (same as /sbin/shutdown - h now) as the command.
https://man.freebsd.org/cgi/man.cgi?shutdown(8)

You can also use the driver route with:
/usr/local/sbin/upsdrvctl shutdown
https://man.freebsd.org/cgi/man.cgi?query=upsdrvctl&sektion=8&manpath=freebsd-ports

@MikeO3 thanks for the info, but do you know what the current/default shutdown command is?

Default is blank no action for every system I have installed. Admin decides on the action to be taken. For my use case, poweroff works.

It is blank, but a shutdown command is issued, so the tooltip says. This field just says you add your own custom one.

Is the tooltip wrong and there is no default shutdown command?

Also interested in this. Are you on scale by any chance? My tooltip says something else and im on CORE.

I am using SCALE.

Can you post a screen shot of the CORE tooltip please.

the default shutdown command in SCALE is:

/sbin/shutdown -P now

and can be found in the code here:
