-    "The Unix system and the shell predate most computational interfaces (e.g. the graphical user interface). Although very old, Unix based systems and the shell are one of the most powerful ways to use computers whether it is your laptop or a supercomputer. This course is an introduction to navigating your way around the shell and demonstrating how it can improve your workflow. This can be in the form of data processing, executing code, using a huge range of built-in tools, and creating pipelines.\n",
