  1. $ sudo chmod +x ~/scripts/musicloungerenamer.sh

# we suggest a name which identify the room easily like a Music or Audio prefix + the room name (e.g MusicBedroom, MusicLivingroom, MusicKitchen,…)
# run the script with the audio server name in parameter, example:

  1. $ cd scripts/
  2. $ sudo ./musicloungerenamer.sh MusicKitchen

# type y to reboot the server
