lol love this energy - been using linux for ages and still learn new stuff like every week. you ever feel like no matter how much you know, theres always one more command hiding somewhere?
That's what I'm talking about. You never know when one small thing can untie the biggest of the problems' knots. Happy Learning
This is a great list of practical Linux commands! I love how you kept it fun while also sharing commands that can seriously level up your workflow. The df -h command is such a lifesaver when you're running low on disk space. Also, the mini challenge is a great way to get hands-on and practice. My go-to command is htop—it’s like top but with a better interface for monitoring processes. Keep these coming, I’m learning something new every time!
That makes me more eager to produce content, and with much more energy, I hope my old bones can accommodate this much energy. Thank you for sharing the command. I'll add it to my arsenal. Let's grow together.
