What Were Your Biggest Mistakes When Starting Out with Linux?

I accidentally ran 'rm -rf /*' once. Fortunately, I had backups ready, but the panic I felt was unreal. It's a mistake everyone seems to share!

At first, I used sudo for everything without really understanding what permissions I was messing with. It took a bit to get a grasp on how to manage permissions properly.

I remember my first weeks trying to exit Vim. I had to kill it from another terminal because I didn't know the proper exit command yet! It's funny how we learn the hard way.

Back in around 2000, I installed Linux on our family computer and ended up wiping everything in the process! That was just the start of many mistakes I made while trying to figure things out.

My worst moment was when I downed a crucial interface on a live production system, cutting off my SSH session and leading to some very unhappy phone calls. I learned to be much more cautious after that.
