I’m new to the Linux programming scene, I’m a chemist but have been learning as a hobby and did a little BASIC and Pascal as a child, and from my experience and research the best three steps are:

1. sudo apt install nano

2. nano [filename]

3. ctrl+x

I’m being somewhat facetious, but haven’t enough knowledge to know if it’s better/powerful than nano, still a real green noob.
