Summary

Description

In this video, we explore the Linux file system structure — the essential framework that organizes everything on a Linux machine. You'll learn what each top-level directory does, why it exists and how it fits into the bigger picture of the operating system.

From /bin, /etc and /usr to /home, /proc and /var, we break down all the key directories with clear visuals and easy-to-understand explanations. Whether you're a beginner or brushing up on your Linux knowledge, this video helps you navigate the file system with confidence.

This layout follows the Filesystem Hierarchy Standard (FHS), a key guideline that ensures consistency across different Linux distributions.

We'll also discuss how these directories are grouped by purpose, what you should and shouldn't modify and how understanding them can improve your Linux skills — whether you're using the terminal, writing scripts or managing a server.
