sorts torrent files into folder by tracker. Just put all your files in a folder called torrents and run this file one level above that folder.

sort.rb

require 'bencode'
require 'fileutils'

Dir.glob('torrents/*.torrent') do |item|

  if File.directory?(item)
    next
  end
  tracker = BEncode.load_file(item)["announce"].gsub("http://", "").split('/')[0]
  if tracker == nil
    next
  end
  Dir.mkdir("torrents/"+tracker) unless File.exists?("torrents" + tracker)
  FileUtils.mv(item, "torrents/" + tracker + "/" + item.split('/')[-1])

end
