# Introduction Welcome to your first Linux lab! This introduction is designed for complete beginners who have never used Linux before. Linux is a free, open-source operating system that powers everything from smartphones to supercomputers. Unlike Windows or macOS, Linux allows users to interact directly with the system through a command-line interface, giving you more control and flexibility. In this lab, you'll learn the basics of using Linux through its command-line interface, called the terminal. Don't worry if this sounds intimidating – we'll guide you through each step, explaining what you're doing and why it's important. <div class="alert alert-warning" role="alert"> <p>If you are new to Linux or LabEx, it is recommended to begin with the <b><a style="color: unset;text-decoration: underline;" href="https://labex.io/courses/quick-start-with-linux" target="_blank">Quick Start with Linux</a></b> course to learn the basics systematically.
