What is Linux?

Linux is an operating system, much like Windows or macOS, but with a few key differences that make it a unique and powerful choice for many users.

Its story begins in 1991 with its creator, Linus Torvalds. Torvalds started Linux as a personal project, a “hobby that won’t be as big and professional like GNU.” However, what started as a small-scale endeavor quickly grew beyond his expectations. Today, Linux is a globally maintained project with over 14,000 contributors, running on 96% of the top one million web servers and 85% of smartphones.

How could a mere hobby project transform into a globally recognized powerhouse of an operating system?

This is the first key difference between Windows / MacOS and Linux. Linux is open-source. This means that anyone with the skills and interest can contribute to its development, leading to a rich ecosystem of different versions, or ‘distributions’, tailored for various needs: Ubuntu for beginners and servers, Arch Linux for cutting-edge software, Kali Linux for security professionals, Rocky Linux for enterprise use, and so on.

Another major difference is flexibility and security. It just has a better developer experience. Users can tweak almost every aspect of the operating system to suit their needs, from the appearance and layout of the desktop environment to the underlying system services and kernel behavior, and even the file system! And that’s why even though Linux makes up only 2.94% of global desktops, nearly half of software developers call Linux their preferred development environment.

For those interested in pursuing a career in System Administration or DevOps, learning Linux is crucial. It’s the backbone of many servers and cloud infrastructures, making familiarity with Linux a highly sought-after skill in these fields.

On a personal level, using Linux can be a rewarding experience for those who love to explore and tinker. It’s also a great way to revive older computers, as many Linux distributions run smoothly on less powerful hardware, giving your old laptop a new lease on life.

How I use Linux

Wanna know my personal experience switching over to Linux from Windows? For the ten or more of you who are interested, I’ve been using Arch Linux as my daily driver for more than a month now, and I have to say I really enjoy how free it is. Not free as in free lunch, but rather free as in freedom. You don’t need to fight against the operating system just to change a certain feature or look. Plus, the command line is really handy to use as a developer, and many important development tools were made specifically for it.

If you’re planning on using Linux on your personal computer, I should caution you that it might be frustrating at first. However, I guarantee it is worth the effort — even if you decide it won’t replace your main OS anyways. Make sure to consult the forums and wiki if you need help, the Linux community welcomes all.

BCG Stats

• All courses in this ranking are free or free-to-audit
• Four of the courses offer free certificate or badge upon completion
• More than 14K people are following the Linux subject on Class Central.

Best Comprehensive Text-Based Introduction to Linux for Beginners (Linux Foundation)

The Linux Foundation’s Introduction to Linux stands out as a supremely detailed, beginner-friendly, and free-to-audit course, available in English and Spanish.

Whereas other courses brush over the small details, this 14-weeks long text-based course assumes nothing and instead meticulously guides newbies through Linux’s nuances, including the graphical user interface often overlooked by most Linux courses.

Thus if you’re someone who plans to use Linux as their daily driver or hoping to secure that juicy system administrator job, this course will help you achieve just that!

What will you learn in this course?

First, you’ll introduce different Linux families (Red Hat, SUSE, or Debian) and their philosophies. You’ll pick one, install it, and then explore its basic system startup processes, graphical interface, and system settings. It may look and feel familiar Windows or MacOS, but don’t be fooled — there are major differences underneath the hood.

For instance, working with the command line is a fundamental skill for any Linux user. You’ll embrace the terminal and discover how you can automate tedious tasks with Bash scripts. You’ll also learn how to navigate your file system with it, and even customize user environment customization, manipulate text with text editors, troubleshoot network-related problems, and all other sorts of advanced operations just by writing and executing commands!

Graded exercises are only available to verified learners. Though there are ungraded exercises like Try-It-Yourself exercises and labs, I recommend that auditors supplement this course with other practical courses in this BCG.

Best Comprehensive Video-Based Introduction to Linux for Beginners (Linux Foundation)

Introduction to Linux – Full Course for Beginners is basically a video-fied version of the course above. But in case you skipped my course description, this freeCodeCamp course is designed for computer users new to Linux, whether they’re working in an individual or enterprise environment.

There are a few differences from the previous course, which are:

1. It’s taught by Beau Carnes, the introduction guy you see at the start of every freeCodeCamp course
2. It’s video-based (duh) instead of text-based
3. It’s completely free, no resources hidden behind paywalls
4. There aren’t any labs or exercises. But let’s face it; there aren’t many exercises if you’re not paying for the cert, so it’s a non-issue
5. There aren’t any certifications to be earned for this course, since it’s a YouTube video.

Thus, take this course if you prefer learning from an audiovisual format or don’t have cash on hand to pay for a certification. You can always supplement this course with other courses or exercises.

And don’t feel guilty that you’re technically taking this what-was-paid course for free — it had the blessings of the Linux Foundation in the form of a grant. It’s A-OK!

Best Interactive Gamified Linux Course for Beginners (Boot.dev)

If you learn best by doing, not just watching or reading, Boot.dev’s Learn Linux course transforms the intimidating command line into an engaging game where you level up while learning commands on your own terminal.

Unlike traditional video lectures or text-heavy tutorials, this course has you work directly in your actual terminal. You’ll type bash commands, execute them on your machine, then copy the output and paste it into each lesson to verify your progress.

The gamified structure keeps you motivated through what could otherwise feel like dry command-line fundamentals. You’ll tackle quizzes that test your theoretical understanding, then immediately apply those concepts by executing commands on your own system. The course covers essential territory developers need: navigating filesystems, managing permissions, executing programs, connecting stdin/stdout with pipes, and using package managers like Homebrew and APT.

You can access all course content free to preview the material, but unlocking the full interactive experience—including answer verification and progress tracking—requires a subscription.

What sets it apart?

• Hands-on approach where you execute real commands in your actual terminal
• Gamified progression system that makes learning command-line tools feel like leveling up
• Immediate feedback loop: execute commands locally, paste output, verify progress
• Covers practical developer workflows: dependency installation, PATH configuration, CLI tools like grep and find
