Don't promote the /^\.{1,2}$/ meme. It doesn't work against malicious people who create files named ..\nfoo. For that you have to use \z instead of $, and by then it is starting to become quite unreadable.

It is much better to write

  next if $file eq '.' or $file eq '..';

Of course, a pendant might also go as far as saying

  next if $file eq File::Spec->curdir or $file eq File::Spec->updir;

Personally I don't bother with that, but it does make for nice cross-platform code. See special directory entries for another thread on the question.
