In the world of cybersecurity, the Graphical User Interface (GUI) is a luxury you rarely have. When you compromise a remote server, manage a cloud instance, or analyze a headless virtual machine, the Command Line Interface (CLI) is your only window into the system.
The Command Line module bridges the gap between point-and-click users and true system operators. You will learn how to navigate file systems, manage processes, manipulate text, and automate tasks using both Linux Bash and Windows PowerShell. We will cover essential commands, piping, redirection, and permission management.

By the end of this module, you will be completely comfortable operating in a pure text environment, giving you the speed, power, and remote-control capabilities required for penetration testing, incident response, and system administration.
