That looks a little weird with the minus in the middle of the character class. Makes it look like a range. I'd sooner write that as

if ( $dir =~ /[^\w-]/ ) {

I was (mistakenly) under the impression that a character class that ended with a dash was a syntax error, because perl treated it as though it were an unfinished range. After reading your post, I tried it in Perl, and of course it works fine. So, I thought it must be an AWKism, but no, it works there too. In short, I have no idea why I thought you couldn't end a character class with a dash. Lets just say it must be an age thing. Thanks for the enlightenment.	[reply] [d/l] [select]
