You’re basically an admin once you know these 6 Linux permissions commands

I once locked myself out of my files with a simple mistyped command. This was the first time I rendered my Linux installation unusable, and it was because I didn’t understand permissions. While I stared at my terminal, I felt like a guest in my own system. That moment taught me that on Linux, control is earned, not given, and I needed to pay the DIY price of using Linux.
