i came here to say this. I was really frustrated for a while figuring this out and understanding how it really makes things more secure, even if you’re the only one using the computer. At first it drove me nuts when my server would auto create a folder for media and I’d attempt to change some files within and not have permission, like, my account should have access to everything.
Changing access permissions without understanding how/why completely borked my first install by setting a user without sudo privileges as primary (or something, I still don’t know what I did haha) but I couldn’t sudo anything and was locked on that profile.
I started by just using Nautilus but this is not good practice so I learned the basics and it finally started making sense.



Haha same thing for me. -R was a game changer
