I have text files with account names. I have a setup so that when something completes in one file it gets moved to another file to run. Though an issue I'm finding is sometimes an account won't get moved to the other file and will get lost in the ether somewhere. But I don't know which account gets lost since there are lots of accounts in each file. I only find out because I know what the total is supposed to be of each file I just find one missing. So how can I somehow compare lists to find the missing one? Because I have the master list with all of them, and the two files; of incomplete and complete. Scrapebox only compares urls afaik? So what can be the tool for the job?
