This is a Linux beginner's textbook intended for use in a three-credit, semester-length course. Some familiarity with graphical user interfaces (GUIs) and command line environments is assumed. The subject matter is approached from both the GUI and command line in order to accommodate different learning styles. Those students who have experience with Microsoft's Windows products will be able to adapt to Linux easily. The topics range from rudimentary to advanced. The advanced material covers elementary commands for shell scripting and some local administrator tools.
