cat users.txt | grep admin | cut -d: -f3Objective Extract the third field of the admin line in users.txt.
Stuck?
Take it one step at a time. Ask for a hint here, or type help in the terminal to
see the commands this challenge is about. Typing hint works there too.
That is every hint. If you are still stuck, run help in the terminal.
