The above image mainly helps you understand the hierarchical structure of the Linux file system and its importance.Previously, the Linux file system was like a chaotic small town where people could build houses wherever they wanted. However, in 1994, the File System Hierarchy Standard (FHS) was introduced, bringing order to the Linux file system.By adopting standards like the FHS, software can ensure a consistent directory layout across various Linux distributions. However, not all Linux distributions strictly adhere to this standard; they often incorporate their unique content or cater to specific needs.To master this standard, you can start by exploring hands-on. Use the “cd” command to change directories and the “ls” command to list directory contents. Think of the file system as a tree, starting from the root directory (/). Over time, this will become second nature, making you a proficient Linux administrator.
