in thread ignore duplicates and show unique values between 2 text files

However, I fail to see why the two column example is functionally different than a full line comparison. "261293\t'snow > equipment > goggles'" will equal "261293\t'snow > equipment > goggles'" just as much as the two substrings would. Are you dealing with a case where the numbers change and you need to be insensitive to that?

Yes, I totally agree, the same code should just work as well.
