Linux is a term that we are hearing more often lately, but what is it? In this course, instructor Grant McWilliams explains what Linux is and how it differs from other operating systems, then walks through how to install it to a virtual machine and use it. Grant tells you about Linux and its history and gives you an overview of the versions—called distributions—of Linux that are available. He goes over virtualization, including how to install VirtualBox and create a virtual machine in VirtualBox. Once you’ve created and optimized your virtual machine, Grant steps through installing and configuring Enterprise Linux, including the GNOME 3 desktop. He concludes with useful advice on how you can install popular software from third-party repositories in Linux and how you can customize your GNOME 3 desktop.

Gain a more thorough understanding of the shell and system processes to help you work faster and more efficiently in Linux.

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.
