Do not attempt to remove the . and .. entries with a regexp, because you will no doubt get it wrong, and cheaper alternatives exist. A reasonable way to get rid of them is:

  next if $_ eq '.' or $_ eq '..'

An even more reasonable way is to isolate yourself from cross-platform diffences by using File::Spec.

  next if $_ eq File::Spec::curdir or $_ eq File::Spec::updir

See Re: Is readdir ever deterministic? for the canonical question and answer on the subject.
