LabEx
Learn Linux, DevOps & Cybersecurity with Hands-on Labs
We recently launched a new Challenges page for LabEx:
The goal is to make Linux practice more structured, measurable, and closer to real-world problem solving.
For many learners, Linux education usually starts with tutorials, documentation, or guided labs. These are useful for building familiarity, but they do not always answer a more practical question: can the learner solve a problem independently in a real terminal?
That is the gap LabEx Challenges is designed to address.
Each challenge runs in a real hands-on environment. Users are given a task, a system state, and a set of checks. They need to inspect files, run commands, debug issues, configure services, or fix broken systems. Instead of choosing an answer, they have to make the environment pass verification.
In that sense, the experience is closer to coding challenge platforms, but focused on Linux and infrastructure skills. Think of it as LeetCode for Linux.
The new Challenges page brings these exercises together in one place, including collections for Linux, Docker, Kubernetes, DevOps, Cybersecurity, and more. Some challenges focus on basic command-line usage, while others simulate operational tasks that are closer to what users may face in production environments.
Our broader idea is simple: guided labs are good for learning new concepts, while challenges are better for testing whether those concepts can be applied without step-by-step instructions.
Learn in Labs. Prove it in Challenges.
Linux Journey has been one of the most popular free resources for learning Linux since 2015.
Created by Cindy Quach, the project has helped millions of beginners take their first steps into Linux through simple lessons and quizzes.
Today, Linux Journey is officially part of LabEx.
The original Linux Journey website (https://linuxjourney.com) now redirects to https://labex.io/linuxjourney.
Our goal is straightforward: keep Linux Journey free, open source, and actively maintained for the next generation of Linux learners.
We'll continue maintaining existing lessons, fixing issues, improving translations, and adding new beginner-friendly content over time.
The official repository is now maintained by the LabEx team:
https://github.com/labex-labs/linuxjourney
We've also recently launched the Linux Journey iOS app, making it easier to learn Linux on the go:
https://apps.apple.com/app/linux-journey/id6770861660
Most importantly, nothing changes about what made Linux Journey special.
It remains free. It remains open source. It remains community-driven.
A huge thank you to Cindy Quach and all contributors who helped build Linux Journey into one of the most loved Linux learning resources on the internet.
We're honored to continue the journey.
