File file1.txt contains lines like:
File file2.csv contains lines like:
I want to filter file2.csv removing all lines where the value of hash is present also in file1.txt. That's to say:
cat file1.txt | extract <hash> | sed '/<hash>/d' file2.csv
or something like this.
It should be straightforward, but I seem unable to make it work.
Can anyone please provide a working pipeline for this task?
