Docs

Here are some limited docs for those who need them.

Installation

• Copy the code above to a file (preferably within your path)
• Install Ruby - there are countless tutorials and examples on the web, on how to do this for your operating system if it doesn’t already have Ruby installed.
• Install the 2 required gems

gem install fileutils
gem install colored

• Modify the DIRECTORIES array to reflect where your movie libraries are located. If you are on Windows it will be something like C:/Path/To/Movies, etc.

Usage

ruby /path/to/find_duplicate_movies.rb

The script will simply collect all of the movie filenames (without extensions) into an array and count the occurrences. If there are more than 1 occurence, it qualifies as a duplicate.
