I’m a good chemist, but not IT advanced. Started using Debian out of the box last year on miniPC. Running Jellyfin only on that local machine. Don’t understand coding, but copy/ paste terminal instructions from trusted sites. Have 1TB music, films and documents. Want to move all photos from Google.
I believe putting in the effort to understand the man format is a great start. Man was made to be helpful and nearly universal.
I second the idea of breaking down the commands mentally and understanding how CLI really works. You don’t need to go super deep but some stuff like $PATH and general bash or zsh will 100% make everything a breeze. These are tools like swinging a hammer you have to learn the motion.
