Is there anyone in here who has experience with the command "diff" in linux,
I have a list with names "names.txt" and i have a list with names that should be removed from "names.txt" and it should generate an output of names.txt with the names from the remove list removed.

Well this will still leave the second duplicate in the list.

lol, yes it will.

you want to use comm, not diff.

comm -3 names.txt remove.txt > clean.txt

Usage: comm [OPTION]... FILE1 FILE2
Compare sorted files FILE1 and FILE2 line by line.

With no options, produce three-column output. Column one contains lines unique to FILE1, column two contains lines unique to FILE2, and column three contains lines common to both files.

-1 suppress lines unique to FILE1
-2 suppress lines unique to FILE2
-3 suppress lines that appear in both files

I was wrong. Didn't know the -u option, but the comm command seemed perfect for this. Congrats, you've been a real prick about it. Always good to know who the assholes are.

Both lists will need to be sorted when i use the comm command, right ?
