Say I have two files. file1.txt and file2.txt
Both files contains a list of shoe brands name (1000+ names), like this:
brand1 brand2 brand3 brand...
Now - I want to compare file1 to file2, delete all the reoccurring entries and only show me Whats in files1 that's not in file2 and vice versa.
The goal in other words is to see what's not in the opposite file since these entries is going to be typed manually into a product backoffice for two different categories so that they'll match/be the same in the end.
