Sync Steam game-data to Google Drive folder

steam_sync.rb

#!/usr/bin/env ruby -w

USER = `whoami`.chomp

SOURCE = "/Users/#{USER}/Library/Application Support/"
TARGET = "/Users/#{USER}/Google Drive/Backups/Steam/in Application Support/"

class String
  def shell_safe
    self.gsub(/(\s)/, '\\\\\1')
  end
end

Dir.foreach(TARGET) do |dir_name|
  unless dir_name[/^\.+$/]

    source_path = SOURCE + dir_name

    if Dir.exist? source_path
      puts "\n#{dir_name}", "--------------------------------------------------"
      puts `rsync -razv --exclude SteamApps #{source_path.shell_safe} #{TARGET.shell_safe}`
    end
  end
end

Expects you to already have the folders you want synced stubbed out in /Users/#{USER}/Google Drive/Backups/Steam/in Application Support/, so it knows what in ~/Library/Application Support is a Steam game.
