"Create a bash script that once executed, plays an audio file from a particular Liquid Galaxy screen. So in total, there are 2 different input variables to consider: input audio file (.mp3) path, screen number. Requirements:

• If the user attempts to play an audio from a screen number that does not exist for the current installation (for a Galaxy of 5, invalid screen numbers would be 6, 7..), make it so the script returns an error message and prompts the user to enter a valid screen number;
• Must include some sort of documentation with instructions on how to execute it correctly (can be a simple text file)."

Task delivery
"Record a short video of your script working. Upload the video to your Google Drive and send us the following:

• Video link;
• Script source code;
• Documentation. Via task dashboard for mentor review and approval. Can be sent as separate files or a zipped file containing all three."
