Problem concerning --> Intent Handling --> Local Command

Hi together,
I need an idea to classify my problem if it is Rhasspy or more Python related. I use the sample modified to my needs and eyerything worked well until i tried to trigger a bash script.

elif intent == “music”:
speech(“Hello, let’s go”)
os.system(‘sh /home/pi/music/’)

As long as i used to run any system command everything was ok. But running a bash script the
speech never happens. I tried also with subcommand but without success. Anyone out there with an idea? Your help is appreciated. Thanks in advance… Jo
