It's in the Dir class, not the File class, which is why you didn't
see it. :)

The easiest way is probably to use foreach and do your renaming in
the block you pass to it:

Dir.foreach(pathname) do
    |f|
    # do whatever you want with f, which is a filename within the
    # given directory (not fully-qualified)
end
