Sorts a collection of files into folders based on the show name. I use this for TV episodes.

sort_movies.rb

#!/usr/bin/env ruby -wKU

require 'fileutils'

TV_DIR = File.expand_path("~/Movies/TV")
EP_PATTERN = /^([a-z\.]+)\.((?:S[\d]+E[\d]+)|(?:[\dx\.]+))\..+\.(?:avi|mkv|mp4|mpg|mpeg)$/i

files = Dir[File.join(TV_DIR,'*')]

files.each do |f|
  next unless File.file?(f)

  base = f.gsub(File.join(TV_DIR,'/'),'')

  if base =~ EP_PATTERN
    show_name = $1.gsub('.',' ')
    show_dir = File.join(TV_DIR,show_name)
    dest_path = File.join(show_dir,base)
    FileUtils.mkdir_p(show_dir)
    FileUtils.mv(f, dest_path)
    puts "Moved #{f} to #{dest_path}."
  end
end
