The command line is one of the most powerful tools you can learn as a developer, and this category is here to make it less intimidating. We start with the basics of navigating the filesystem, working with files and directories, and using essential commands like grep, find, sed, and awk to slice through logs and data. From there you will learn how to chain commands together, build simple shell scripts, and automate the repetitive tasks that slow you down.

You will also see real workflows from live servers, including how to monitor running processes, manage services, and safely edit configuration files from the terminal. Many examples tie into web development tools such as Git, Composer, WP CLI, and system package managers so you can run your whole stack with a few keystrokes. If you want to feel at home in the terminal instead of avoiding it, the CLI articles in this section will help you get there.
