Sharpening My Linux Skills for DevOps: Commands, Concepts & Notes

👋 Hello, peeps!

I wanted to be thorough, do my best, and maybe even become the best source of knowledge — if not for others, at least for myself, right? It’s all about building confidence and really believing in your own skills.

Even though I already had some knowledge of Linux and commands (and yes, I use a fair bit of them at work), I realized I was mostly stuck using just a few common ones. You know the drill — tailing logs, grepping for stuff, quick file edits. It’s easy to fall into a routine and never really explore the full toolbox Linux gives you.

For example, I rarely touched anything related to networking, user management, or system connections — mainly because my work didn’t require it. But I felt like if I really want to grow, I should revisit the foundations and get them right. Because we all know — a solid foundation is everything when it comes to mastering any skill.

🧠 Why I'm Refreshing My Linux Skills

That brings me here: I decided to go back and refresh my Linux knowledge properly — with intention and structure. I grabbed a course on Udemy that I honestly think is incredibly well done:

📚 Complete Linux Training Course to Get Your Dream IT Job in 2025

Every section is detailed and easy to follow — even though I’m watching it at 1.75x speed (don’t judge, it still works 😄).

I actually completed most of the course earlier — I just had the disk management section left. But here's the catch: I had been taking notes directly in Udemy while watching the videos, and it became a nightmare to go back and review them. Scrolling through long, messy text blocks was painful.

So I figured, why not just start over — not from the very beginning like setting up the environment, but from the core command sections — and this time take proper notes in a way I can actually use later. Also, let’s be honest — part of me was punishing myself for not doing it right the first time 😅.

📝 Sharing My Notes (You're Welcome 😉)

As I’m going through the course again, I’m now creating clean, structured notes in Markdown format — easy to read, easy to revise, and perfect for anyone else who wants to follow along.

You can find my notes here (WIP):

🚧 Disclaimer: These notes are not yet complete. I’m currently at Section 5 of the course and will be updating them regularly over the next few days.

🛣️ What’s Next

My goal is to finish the entire course by the end of next week and then move on to Git.

Now, Git is something I already use and understand to some extent, but I want to go deeper — refresh the basics and build a stronger, more complete understanding. Because again... strong foundations matter.

🔑 A Quick Tip for Anyone Studying

When you're learning Linux — type out the commands. Practice is everything. Use man or --help if you get stuck or want to dig deeper. Even in the future, it’ll save you tons of time. 🙌
