Need Help??

This regex, I think, will match . or .. and nothing else:

/^\.{1,2}$/

Good thing you're just "thinking". It also matches ".\n" and "..\n", thanks to $'s little-understood feature of matching before the optional newline at the end of the string. Perhaps you want `/\A\.{1,2}\z/` [download] -- Randal L. Schwartz, Perl hacker	[reply] [d/l]

This is true, and that would break the script :( Remember that `$item` has been prefixed by the directory, so we want to filter out elements like `foo/bar/.` and `fi/fo/fum/..` Better would be to extract the file name and compare it to current/parent directory in a portable fashion. this will work on *nix or windows. I have no idea what it might do on a MAC or on VMS.	[reply] [d/l] [select]
