While the Linux operating system works with a graphical desktop interface much like Windows or macOS, with Linux, most of the system administration is done in the shell. Using the command line in the shell gives you the power to do tasks that would be more difficult using other methods, so having a solid grasp on how to use the shell can help you work faster and be more productive. In this course, Grant McWilliams provides an introduction to the Linux command line. He teaches you how to customize your shell, and shows some powerful shell tricks and shortcuts that can increase your speed and efficiency using the command line. Grant also explains how to create complex administration tools by stacking together simpler commands using named and unnamed pipes and redirects; how to start, pause, and end processes; and how to schedule one-time jobs and recurring jobs, and more.
