The Linux file system was like a messy town. People built their houses wherever they wanted. But in 1994, a new guideline called the Filesystem Hierarchy Standard (FHS) was made. This helped organize the Linux file system.

FHS was like a library classification system for Linux. It provided a consistent structure across distributions, so developers and admins could find things. But does every distro follow it exactly? Not always. Some add custom tweaks for specific user needs.

To get good at using the Linux file system, you can start by exploring it. Use commands like "cd" to move around and "ls" to see what's in each directory. Think of the file system as a big tree, with the root (/) at the bottom. Have fun exploring the Linux file system.
