I am trying to strip a few characters from the end of my hash keys. Here's what I have, but it's not working: 
$db_results{$_} = $1 if $db_results{$_} =~ /(BLAH\d{2}-\w)/ for keys $
+db_results;

Say the hash key is BLAH01-A05AFGH. I want the hash key to be BLAH01-A.

I assume this one is not too hard and that the fellow monks would know how to accomplish it.

UPDATE Sometimes I post a question and 10 minutes later answer it myself... 
foreach (keys $db_results) {
    my $match = $1 if $_ =~ /(BLAH\d{2}-\w)/;
    $db_results->{$1} = delete $db_results->{$_};                     
+        
}

Putting the code here for anyone interested. Probably a better way to do it too, which I'd always be interested in. It's a hash of hashes and it kept my data structure intact, so that's good too.
