in thread Create a list of directories without . and ..

You are correct about . and .. - getting a regex to match them reliably is far trickier than it looks. The obvious m/^\.\.?$/, for instance, will give a false positive on "..\nsubdir". Much safer and simpler to just test on ($_ ne '.') && ($_ ne '..'). (BTW, != is numeric. Use ne for strings.)

    No, only on "..\n" and ".\n".
