I have organised the compilations in my music library with the following structure:
Every file in the directory has this naming convention:
The script should search for the compilations and identify them automatically.
Then, every file in directory cd1 should be renamed to 1-<nn>_<title>.mp3 (e.g. 1-01_hereisthetitle.mp3), and every file in directory cd2 should be renamed to 2-<nn>_<title>.mp3 (e.g. 2-01_hereisanothertitle.mp3).
Can you provide some input for the syntax of a bash script performing this task?
