Of course! Here is a well-commented and robust shell script that accomplishes the task. It's designed to be safe, handling filenames with spaces or special characters, and provides clear user feedback.
Key Features of this Script:
Robust File Handling: Uses find -print0 and read -d '' to safely handle filenames containing spaces, newlines, or other special characters.
Clear Argument Parsing: It checks for the required arguments and provides a helpful usage message if they are incorrect.
Dynamic find Command: The script builds the find command dynamically and safely, whether you provide extensions or not.
