Shutdown and Power Off Delay

[Techstyle]

OpenPlotter is already doing that running this service when a shutdown GPIO is defined in openplotter-settings: https://github.com/openplotter/openplott...hutdown.py

but your approach is very interesting. gpio_shutdown_command is not documented anywhere, where did you get it from?

Add -15 argument to your commands to make sure the configuration files are saved before exiting:

pkill -15 opencpn

Thanks for the '-15' I will add it, although, it seems like Openplotter has it covered - I didn't know that, I see your solution is only shutting down OCPN, could the feature request be to add more applications?  for me OCPN and Chromium is desirable, but is there a way to safely close all open applications before closing or have check boxes for common ones?

as for "gpio_shutdown_command is not documented anywhere, where did you get it from?" 

it must be somewhere... https://www.perplexity.ai/search/my-rasp...7nok1aA6Tg
