11 Best Linux Courses in 2026, Tested and Ranked

Lane wrote that he had to teach himself the command line during his CS degree... university kinda just threw him to the wolves on that front. Meanwhile his advanced algorithms professor believed that if you weren't using Linux and Make to compile C++, you were too far gone to deserve help. I actually had a similar experience, and I know plenty of developers pick up Linux that same accidental way, so I'm a bit picky about this list. Here it is:

Prices are from each site when I checked in October 2026, but keep in mind Udemy's sale price changes constantly.

How I ranked these

1. Do you type real commands?
2. Does it teach what developers actually use?
3. Is the free part useful on its own?

Linux is muscle memory. You can read about cd .. all day, but it probably won't stick until you've typed cd into the wrong directory and had to find your way out (26 times). So a course with a terminal, and especially one that tells you when you got it wrong, ranks above those that only explain.

I also care about the second one because this list is for developers, not sysadmins. In Lane's article on his dev setup, he was mostly on a Mac, used WSL and Ubuntu on his gaming PC, and deployed with Docker on Debian servers. A developer needs the shell, files, permissions, processes, and packages much more than they need to configure a printer on a local network.

What our data says about learning Linux

Stack Overflow's 2025 Developer Survey raw data. I downloaded the response file and filtered it to the 23,025 professional developers who answered the "work operating system" question. 49.5% of them used a Linux distro at work, compared to 52.2% using Windows and 39.1% macOS. Counting WSL, it's 56.5%.

Now, it does depend a lot on your job. Some rows combine closely related survey roles, and one person can pick more than one:

And even among professionals who used no Linux and no WSL at work, 36.6% still used Bash or another shell. If you're going backend or DevOps, Linux isn't optional. If you're going front-end or mobile, you need a good shell, but it doesn't need to be Linux.

Boot.dev: Learn Linux

Boot.dev is first because it's ours and it's built for people who want to be developers. If you want a broad, vendor-neutral Linux intro for free, LFS101 is the better choice.

Learn Linux is 7 chapters and 66 lessons, about 10 hours. You play a "forensic developer" investigating a security breach at a fictional bank, using nothing but the command line. Chapters cover the shell, the filesystem, programs, input and output, permissions, editors, and package managers.

You can try it without an account. The "write some code" button on the course page asks one question and then drops you into a live shell. The first task is echo "I use Linux btw". I typed ech instead, got bash: ech: command not found, and the submit check failed with "No matching transcript command found containing 'echo'."

About half the lessons are in that browser shell, 18 are multiple choice, and 15 have you run commands on your own machine and paste the output.

The cons:

• The browser shell isn't a full Linux box. It's an emulator, so uname, ps, and sudo return "command not found." Processes, permissions on your own files, and package managers come later in the course, on your own machine.
• Most of it is paid. The demo is three lessons. With a free account, the first three chapters (31 lessons) are fully interactive. After that it's read-only unless you pay $59 per month or $399 per year.

Seeing as it's our course, I'll also share some stats. 50,736 people submitted their first Learn Linux lesson between July 2025 and March 2026. 75.4% of them had passed a lesson in another Boot.dev course first, most of them in Learn Python (70.3% of all starters). That's partly because our backend path puts Python first, but it's the order I'd recommend anyway. Learn a language, then learn the environment your code runs in.

It's also a short course. The 22,711 people who finished it between October 2025 and September 2026, a different window from the starters above, took a median of 5 calendar days from their first lesson and were active on 4 of them. For most people, mastering the basics takes days, not months.

The Linux Foundation's LFS101: the best free course

Introduction to Linux (LFS101) is from the organization that sponsors Linux itself. It's 60 hours of material with labs, free on the Linux Foundation's own training site, and finishing it gets you a free digital badge.

The cons:

• Same course, two prices. On edX, the verified certificate for the same course is $209. Take it on the Linux Foundation's site.
• You can't see anything before signing up. The "Enroll Today" button goes straight to a sign-in wall, and access lasts 90 days.
• It's broad. 3 of its 18 chapters cover the desktop interface or printing, which a developer can skip.

The Linux Command Line: the best free book

William Shotts's The Linux Command Line is a free 597-page PDF and the most completely free text on this list. Its first exercise has you type some gibberish into your terminal on purpose, just to see "command not found." Frankly, it's a good first lesson: the terminal's error messages aren't scary!

The cons:

• It's a book. Nothing checks your work, so you need the discipline to type along.

OverTheWire Bandit: the best free practice

Bandit isn't a course. It's a wargame with levels 0 through 34, where each level's password is hidden somewhere on a real Linux server that you log into over SSH. Level 0 is literally "connect to bandit.labs.overthewire.org on port 2220."

I did. I typed cat Readme and got "No such file or directory," because Linux filenames are case-sensitive. cat readme worked. VERY fun, very interactive.

The cons:

• You need SSH first. Windows users will want WSL or a terminal app with SSH before level 0.
• Walkthroughs are discouraged. The server's login banner asks players not to post spoilers or writeups. They exist anyway, but if you read them you skip the part where you learn.
• It's not a course. Bandit is more of a challenge or game than a structured class. For some people, that might be what you want.

Linux Journey: free, now on LabEx

Linux Journey used to be its own site, and linuxjourney.com now redirects to LabEx. The lessons are still free text cards with multiple-choice checks. A wrong answer shows an explanation, and you can't continue until you pick the right one.

The cons:

• The terminal mostly wants you to log in. LabEx's free online terminal ran cat /etc/os-release and showed Ubuntu 24.04, but it answered uname, ps, and sudo with "not supported in current session. Log in." It even answered my typo ech that way, where a real shell would say "command not found."
• Upsells. LabEx Pro is $99 per year.

Linux Upskill Challenge: learn on a real server

The Linux Upskill Challenge is 20 daily lessons where you run your own Linux server, either a cheap cloud server or a local VM. It's free, community-run, and closer to sysadmin work than anything else here.

The cons:

• Setup is on you. The free in-browser option through Killercoda needs a sign-in and doesn't support Day 12 yet.
• Some notes are dated. One setup note still points to a Debian 11 server.

MIT's Missing Semester: free, broader than Linux

The Missing Semester of Your CS Education is MIT's free class on the tools CS programs "forget to teach". The 2026 edition even added a lecture on agentic coding. Very modern.

The cons:

• Only 2 of its 9 lectures are about the shell. The rest cover editors, Git, debugging, and more. Great class, but not a Linux course on its own.
• No solutions. Exercises come without published answers (at least as far as I could find), and some notes still show 2020 sample output.

Learn Linux in 5 Days: the best-selling video course

Jason Cannon's Learn Linux in 5 Days is the Udemy course every other list puts first. The free preview I watched covers distributions with AlmaLinux and Rocky Linux slides, then installing VirtualBox.

The cons:

• It's shorter than it looks. Udemy lists 13 hours and 40 minutes, but 6 hours and 57 minutes of that total is 29 downloadable slide decks, not video.
• Practice is up to you. You install a VM, and nothing checks the commands you type in it. It's basically a sandbox.
• Never pay list price. It listed at $139.99 and was $19.99 with a coupon that Udemy added to the URL on its own.

Cisco NetAcad: free courses toward a real exam

Cisco's Networking Academy has two free Linux courses: Linux Unhatched for a short intro and Linux Essentials for the full thing, with some free badges. Linux Essentials lines up with the Linux Professional Institute's Linux Essentials exam, which costs $120.

The con: I couldn't see a lesson. The first click on either course is an account wall, so I can't tell you how its labs feel.

Codecademy: Learn the Command Line

Codecademy's Learn the Command Line is a short, beginner-friendly course in Codecademy's usual lesson-plus-editor format.

The cons:

• Sign up before anything. "Start" opened a sign-up form, so I couldn't try the terminal without creating an account.
• Even after signing up, I needed a trial. I couldn't sample any lessons without choosing a plan and starting a free trial with a credit card.
• Certificates are paid. Plus is $14.99 per month billed yearly or $29.99 monthly.

Red Hat: Fundamentals of Red Hat Enterprise Linux

If you're headed toward enterprise Linux and eventually the RHCSA, Red Hat's Fundamentals of RHEL is free to audit, with a $99 certificate. Red Hat's old free RH104 page is gone.

The con: it's Red Hat-flavored. Great if your job runs RHEL, less useful if you're deploying to Ubuntu or Debian... you know, like most developers.

Also worth knowing

• The Linux PATH variable: the single most common thing new developers break on their own machine.
• Linux file permissions: chmod explained without the octal headache.
• Shell vs. terminal: the difference, since Linux Journey's very first quiz asks.

Which Linux course should you pick?

• Learning Linux to become a developer: Boot.dev, ideally after your first programming language.
• Want a complete free course and a badge: LFS101, on the Linux Foundation's site, not edX.
• Learn by reading and typing along: The Linux Command Line (book).
• Already know a few commands and want to get better fast: OverTheWire Bandit.
• Want to run a real server: the Linux Upskill Challenge.
