I think we are getting off on the wrong foot here.
Let's move on from stuff unrelated to the question if possible.
Just FYI there is a Linux app for lighting called LEDSpicer that also handles automation of joysticks and LEDs on Linux. I have it set up for U360s, GGG hardware, servosticks, etc.
I'll take a look at your plug-in. Thanks for posting it. I'm always excited to see more linux contributions
FYI, this is the method for saving a log and also outputting it to console:
attract --loglevel debug 2>&1 | tee ~/.attract/log.txt
That generates a lot of detail, so probably not a good thing to put in autostart.sh
