FILE RENAMER

This script contains three functions and takes up to three arguments:

"-d" is the path to the directory containing the files to be renamed, takes a string. THIS ARGUMENT IS MANDATORY!

"-p" is the prefix you want to remove (for instance other enumeration types), takes an integer representing how many characters will be stripped from the start of the file name.

"-s" is a string to be stripped from anywhere in the file name.

Usage example:

Given the provided example file name: '[01] - Artist Name - Song Name', and our desired outcome: 01 - Song Name', applying the following cmd prompt:

python main.py -d '/.../artist/album' -p 7 -s 'Artist Name - '

will yield the following result:

• '-d "/.../artist/album"' will provide the location of all the files
  
• '-p 7' will select the undesired enumeration of "[01] - ", leaving us with 'Artist Name - Song Name'
  
• '-s "Artist Name - "' will strip everything down to just the song name
  
  
• The script will then enumerate the songs based on the order in the directory, so some form of original enumeration ("Artist Name - Track Number - Song Name", "[Track Number] - Artist Name - Song Name", "Track Number - Song Name" etc.) will be needed to begin with, otherwise songs will be enumerated in alphabetical order.
  
  The final result will then be:

01 - First Song
02 - Second Song
03 - Third Song
etc.

Possible future additions

• Possibility to handle other file formats
