Well, that's still two passes, but it's one line, which gets a ++BrowserUk from me! :-)

    Thanks for your help, but I've realised that I need to do the same problem except that the duplicate may be a particular pattern within an element. So therefore all those elements containing that pattern need to be removed. thanks again, paul

      This should do it if your pattern is can be reliably matched by a single regex 

      my $pattern = qr/a regex that matches your pattern/;
 my @deduped = grep { !exists $count{$_} or $count{$_} == 1 }
               map  { /$pattern/ and $count{$_} ++; $_ } @data;

      What's this about a "crooked mitre"? I'm good at woodwork!
