Re^4: ignore duplicates and show unique values between 2 text files

I think your posted code will not follow the posted spec. The posted lines contain additional whitespace, so my ($number,$article) = split /\s+/, $line will yield
$number = 261293 $article = 'snow

as opposed to split /\t/, $line, which would yield
$number = 261293 $article = 'snow > equipment > helmets'

Update: Parent code updated

#11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.

Well sorry I noticed my problem after I saw your code and updated it in the meantime. =) Anyway considering the bad data the OP showed till now, it's better not expecting '\t' as delimiter... ... at least as long as there is no third column coming into play. =) Cheers Rolf ( addicted to the Perl Programming Language)	[reply]

Not the cleanest problem statements, to be sure. I still want to know why the OP cares that the records contain multiple 'columns'. I tried communicating the code issue via private msg when I spotted it, but you appear to be ignoring me. #11929 First ask yourself `How would I do this without a computer?'

> but you appear to be ignoring me. indeed sorry, =) I wasn't aware that `\ignore` also filters private `\msg`s. (No idea why and when you came on the list...) Cheers Rolf ( addicted to the Perl Programming Language)	[reply] [d/l] [select]
