Remove dups with MD5 hashing

mofile.rb

require 'digest/md5'

h = {}

Dir.glob("**/*", File::FNM_DOTMATCH).each do |f|
  next if File.directory?(f)

  k = Digest::MD5.hexdigest(IO.read(f)).to_sym
  if h.has_key? k
    h[k].push f
  else
    h[k] = [f]
  end
end

h.each_value do |a|
  if a.length > 1
    puts "*****\n"
    a.each { |f| puts f } # File.delete(a[f])
