It would be mildly out of character for me to post what turns out to
be the best way of doing something like this, but here's at least one
way that I think achieves what you want, using Dir.[] (aka Dir.glob):

  def filesUnderManagement
    Dir["#{@dir_name}/*"].reject do |f|
      test(?d,f) || /\.bak$/.match(f)
    end .sort
  end

(Is this too race-condition-infested?  Is there a way around that?)
