Get names of all files from a folder with Ruby

Question

I want to get all file names from a folder using Ruby.

Answer 1

def get_path_content(dir)
  queue = Queue.new
  result = []
  queue << dir
  until queue.empty?
    current = queue.pop
    Dir.entries(current).each { |file|
      full_name = File.join(current, file)
      if not (File.directory? full_name)
        result << full_name
      elsif file != '.' and file != '..'
          queue << full_name
      end
    }
  end
  result
end

returns file's relative paths from directory and all subdirectories
