This text-based course teaches you how to efficiently preview and monitor files using standard command-line tools. You will start by understanding basic file systems and text streams, ensuring you have a solid foundation before executing commands. Next, you will learn how to extract specific lines from the top or bottom of a document, inspect system logs, and monitor real-time data feeds as they update. What you will learn: Understand the core concepts of file streams and terminal output; Use the head command to inspect the opening lines of configuration files; Apply the tail command to view the latest entries in system logs; Monitor live log updates in real-time for troubleshooting; Manage file access safely using basic sudo permissions. This course is designed for absolute beginners who want to build practical command-line skills. No prior Linux experience is required. Start reading and monitoring files like a professional today.
