I have a list of 1000 urls like ebay.com/iue ebay.com/aieruf cnn.com/asdfh subs.ebay.com/sdfhsdf cnn.com/ahjdf I want to remove all duplicate domains. This is possible to do using scrapebox. But the problem is, I want to keep all unique subdomains. meaning I want to treat subdomains as unique domains. for example, in the above list out of ebay.com/iue ebay.com/aieruf subs.ebay.com/sdfhsdf one of the first 2 would remain, the other one would be removed. the third one would remain. How can I do this?
