Linux Essentials
Course Description
Linux is everywhere. It runs the internet, powers the cloud, manages Android phones, and drives supercomputers. Learning Linux is one of the smartest career moves you can make in IT. This free course from Cisco Networking Academy gives you a solid, hands-on foundation in Linux essentials.
You'll start with the basics: what is Linux, why it's different from Windows or macOS, and how to navigate the file system. Then you'll dive into the command line—the heart of Linux—learning essential commands to manage files, processes, users, and permissions. The course also covers system management basics and security fundamentals.
This free, self-paced course takes about 8 hours to complete and includes interactive labs, quizzes, and a final exam. You don't need to install Linux on your computer—the course provides an online terminal environment for hands-on practice. Upon completion, you'll earn an official Cisco digital badge to showcase your Linux skills.

User Reviews
"I was terrified of the Linux command line before this course. I thought it was only for hackers and wizards. But Cisco's course made it approachable. The hands-on labs in the browser were brilliant—no need to install anything. Now I actually enjoy using the terminal. Highly recommended for beginners."
"This course gave me the confidence to apply for junior system admin roles. The module on file permissions was particularly clear. I also appreciated the scripting introduction—just enough to get me started. The Cisco badge looks great on my LinkedIn. Best free Linux course out there."
"Solid, practical introduction. The course focuses on the essential commands you'll actually use. The labs are well-designed and give immediate feedback. I wish there was a bit more on networking commands, but that's probably beyond scope. Still, an excellent starting point. Highly recommended."

💡 Final Thoughts
If you work in IT—or want to—Linux is non-negotiable. The cloud runs on Linux. Most servers run on Linux. Cybersecurity tools run on Linux. This Cisco course is the best free introduction I've seen. It's hands-on (you'll actually type commands), practical (you'll learn commands you'll use every day), and beginner-friendly (no prior experience needed). The built-in online terminal means you can practice anywhere, anytime. By the end, you'll navigate the file system, manage permissions, kill rogue processes, and even write simple scripts. The Cisco digital badge is a credible credential. Don't be intimidated by the terminal. Start here.
