Chapter 4: Understanding the Linux Filesystem
In this chapter, you'll learn how the Linux directory tree is organised, what the main directories contain, how absolute and relative paths work, and the difference between symbolic and hard links.
Welcome to Day 2.
In the first three chapters of Day 1, you learned what Linux is, built a safe practice lab, and became comfortable using the terminal and its built-in help system.
Now you are ready to explore where Linux keeps its files.
The Linux filesystem may look unfamiliar if you are coming from Windows, because there are no C: or D: drives at the top of the directory structure. Instead, everything begins at a single location called the root directory.
Once you understand that structure, moving around Linux becomes much easier.
