Lesson 1 of 8 · The Linux filesystem

Linux filesystem basics

The first thing to accept is that a Linux filesystem is a nested set of directories and files, starting from a single top level called the root directory, /. That single slash is the beginning of the entire filesystem.

A path is the address of a file or directory inside that tree. An absolute path is the full address starting from the root, so it always begins with /.

A relative path is read from wherever you are standing now. If you are inside /home/student and you type cd Downloads, Linux reads that as /home/student/Downloads. If you feel lost, run pwd.

Lab terminal
