You should still require 2 words; otherwise poor Johnson Johnson will suffer.	[reply]

True. What about people with three names, though (names with 'van', for example)? None of my expressions require two words. I suppose I could make it accept 2+ words. Not hard, just need to tweek the ".+"... ah well, it's his own fault or his parent's fault for inflicting such a name on us.	[reply]

Oh, hey, that's cool. I already handed the script over, but if there's huge issue with Jo Jones or John Johnson losing their first names, I can just send my client a fixed version of the script. He's already run the thing, and it's a huge success. :-) Dev Goddess Developer / Analyst / Criminal Mastermind "Size doesn't matter. It's all about speed and performance."	[reply]

`$field =~ s/\b(.+)\b\s\1\b/$1/g;` Beware!* Depending on what else there is in the string ~~after~~ apart from the (possibly repeated) firstname + lastname, this regex can be highly dangerous. Consider: `my $field = "Jo Doe (Tel: 999-111-111)"; $field =~ s/\b(.+)\b\s*\1\b/$1/g; print $field;` [download] Oops! What's happened to Joe Doe's phone number??	[reply] [d/l] [select]

aye, #3 and #4 remove duplicates bits anywhere in the string, as stated in my original reply.	[reply]
