Here's some code to help get you further:

def crawl(current_dir)
  Dir.entries(current_dir).each do |entry|
    if File.directory?(entry)
      crawl(entry)
    else
      puts File.size(entry)
    end
  end
end

Note that this code cut-and-pasted will not work. For example, make
sure you don't visit "." and ".." or you will be in an infinite loop.
Ask again if you still need more assistance.
