Module 3: Core Linux Skills

Chapter 6: Navigating the Ubuntu (Linux) File System

In this chapter, you'll learn how the Linux file system is organized, master the graphical file manager, and gain confidence using the command line to navigate and manage your files efficiently.

In the last chapter, we looked at the GNOME desktop environment and learned how to move around Ubuntu’s interface, use the Activities view, manage your work with workspaces, and customize your desktop's look.

Now it’s time to peek behind the desktop interface and see what’s really going on underneath. Every file, folder, program, and system component has its own place on your computer, arranged in a specific structure.

If you’re used to Windows or macOS, the Linux file system might feel a bit unfamiliar at first, but once you get how it’s organized, you’ll see that it’s surprisingly logical and consistent.

In this chapter, we’ll explore the Linux file system from two angles: through the easy-to-use graphical file manager and the more powerful, hands-on command line.

Here’s what we’ll cover:

  • Understanding the Linux file system hierarchy, where everything lives, and why it’s organized that way.
  • Using the Files application, your graphical file manager for everyday tasks.
  • Mastering the command line, navigating directories with confidence.
  • Essential file operations, copying, moving, creating, and deleting files.
  • Working with hidden files and permissions, knowing what you can and can’t access.

Whether you prefer graphical or commandline, by the end of this chapter, you'll feel comfortable managing files and folders in Ubuntu.
