A short ruby script I wrote to quicken the process of prefixing episodes with numbers on an external hard drive.

number_episodes.rb

#!/usr/bin/env ruby

require 'pry'
require 'fileutils'

EPISODES = [
  nil,
  nil,
  nil,
 "My Happy Place.mov",
 "My ABC's.mov",
 "My Cookie Pants.mov",
 "My New Role.mov",
 "My Lawyer's in Love.mov",
  nil,
  nil,
  nil,
 "Their Story II.mov",
 "My Full Moon.mov",
 "My Soul on Fire, Part 1.mov",
 "My Soul on Fire, Part 2.mov",
  nil,
 "My Chief Concern.mov",
 "My Finale.mov"
]

EPISODES.each_with_index do |ep, i|
  next if ep.nil?

  prefix = i + 1
  if prefix < 10
    prefix = "0" + prefix.to_s
  end

  new_name = prefix.to_s + " " + ep

  puts "moving #{ ep } to #{ new_name }"
  FileUtils.mv(ep, new_name)
end

exit
