For a while now, I have been trying to find a way to do this - surely someone here can provide an answer... I have two text files with two lists of URLs. I want to compare the two and produce a third list that contains ONLY the URLs from list2 that ARE NOT in list1. With all the scrapebox users around, I would think this is a common problem. You have one list of sites that you have scraped or purchased and you post to it. Then you get a second list. You don't want to post duplicates, so you only want the new sites that are in the second list. HOW ARE YOU GUYS DOING THIS? I have tried a programs like WinDiff & WinMerge, but I can't see how to use them to do this type of comparison (especially to automatically produce a third file that is just unique new results).
