The first two lines to match for the current or parent directory could be rewritten as next if $file =~ /^\.{1,2}$/;.

But it would be better not to, because it is a potential time-bomb waiting to explode. Why do people keep dragging out this broken regexp, when a couple of conditionals will do the trick?

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