I'll update the chmod line now thanks for catching that.
Also thanks for the additions. I am trying to keep these at one thousand words so I appreciate the extra info in your comment. I had to pick and choose what to add in this post and where to expand deeply. Naturally things will get left out.
Yeah, I was aware of why you may have left things out, which is why I originally wasn't going to add more, but since you are aiming at beginners, I worry that they might not consider the consequence of just adding sudo to all of their commands.
But then it occurred to me, hey, this place is great for discussion, so I'd add it anyway as a sort of discussion point.
Also, the markdown on your edit is a bit off.
hahaha yeah I noticed that about the markdown when I was reading it over. But yes pleas feel free to bring up something that might not be clear as I go through this. We both know how deep this can be.
