This seems like it'll be awesome but I'm having an issue with the script running successfully within BTT. As a test, I ran the command './btt_stats.rb zoom toggle mute' from the terminal and it worked just fine to mute/unmute Zoom. When I run the script from within BTT I get the following error. Not sure if this is a permissions issue or something else but I'm new to BTT and not sure where to go from here. Any help is appreciated (excuse the error formatting).

Do you have the full path to the btt_stats.rb script in the shell command in BTT?

remark

I originally did have the path incorrect within BTT (pointed to /bin/sh by default), which gave the 'file not found' text on the button itself. I changed it to the absolute path where the btt_stats.rb is located and that's when I started getting the error 13 output.

remark

You can add the buttons using the btt_stats.rb add commands and it will set the paths correctly automatically.

Actually, now I can't remember if I added templates for the zoom buttons to the add command or not…

remark

That did the trick. I did add the Zoom buttons via the add command but the Launch Path was showing as /bin/sh. A quick change to /bin/bash and adding the full path to the 'script' section allowed it to work. Thanks for the help!

Your executable should be bin/bash, arg -c, then the path to the script and its arguments in the script field.
