Linux Command Line and Filesystem Basics
Build comfort with navigation, files, directories, editors, and the mental model behind the Linux filesystem.
Before troubleshooting services and logs, you need to feel comfortable moving around the system itself.
This topic introduces the everyday Linux building blocks: navigating directories, inspecting files, understanding paths, and working safely from the shell. The goal is not to memorize commands in isolation, but to understand what the system is showing you.
Once this topic feels natural, every later Linux troubleshooting step becomes faster because you are no longer fighting the interface.
