Hey everyone, I have a question about comparing two files. I have two lists of files. The first list, todo.csv, lists a series of compounds my supervisor wants me to perform calculations on. The second list, done.csv, lists a series of compounds that I have already performed calculations on. However, the two lists overlap, and I am interested in reducing redundancy. So my question; is there any way to remove all lines from todo.csv that also occur in done.csv? I suspect awk could be used to do the trick, but I am not really sure how. Any help would be greatly appreciated.

Take a look at two commands - COMM and DIFF

Ah, thank you very much. I had no idea the comm command existed.
