Remove lines from .txt gawk
Okay so how do I remove lines from new.txt if they're in tried.txt,
For example, if new.txt contains 123 and tried.txt contains 123, so remove 123 from in.txt and output results to new2.txt.

Using grep:
grep -F -x -v -f tried.txt new.txt > new2.txt
Using awk:
awk "NR==FNR{a[$0];next} !($0 in a)" tried.txt new.txt > new2.txt
Any of the above commands should work for you. See:
