Free online courseBasic Commands in Linux

Course Description

Build confidence in the Linux terminal by learning the basic commands used every day in IT support, system administration, and technical roles. This free online course focuses on the practical skills that help you navigate a Unix/Linux environment, understand what you are seeing on screen, and handle common file-viewing tasks without guesswork. If you are moving from a graphical interface to the command line, these fundamentals make the difference between feeling stuck and feeling in control.

You will learn how to display and inspect file contents efficiently, especially when files are too long for quick viewing. Instead of overwhelming the screen with output, you will practice working page by page, a simple habit that improves readability and reduces mistakes when scanning logs, configuration files, or notes. You will also work with techniques for showing line numbers, including blank lines, which is extremely helpful when troubleshooting, following instructions, or communicating exact locations in a file with teammates.

Another key outcome is understanding how and why the cat command is used beyond simply printing text. You will see how it supports everyday workflows, such as quickly checking what a file contains, combining information, and creating a new file with content directly from the terminal. These skills are small on their own, but together they form a foundation you will rely on in more advanced tasks like scripting, server maintenance, and automation.

By the end, you will be better prepared for entry-level tech jobs, lab environments, and further learning in Linux and operating systems. Whether you are studying for personal growth or building job-ready skills, this course helps you practice clear, repeatable command-line habits that translate directly to real work.
