Why should you learn about Linux? It’s growing in popularity, and it’s inexpensive and flexible. Linux is also a major player in the small and mid-sized server field, and it’s an increasingly viable platform for workstation and desktop use as well. By understanding Linux, you’ll increase your standing in the job market. Even if you already know Windows or Mac OS and your employer uses these systems exclusively, understanding Linux will give you an edge when you are looking for a new job or if you are looking for a promotion. For instance, this knowledge will help you to make an informed decision about if and when you should deploy Linux.
This book exists as a hands-on introduction to Linux with the goal of helping you pass the LPIC-1 or Linux+ exam. Because these exams cover basic Linux command-line tools, software management, hardware configuration, filesystems, the X Window System, the boot process, scripts, security, documentation, administration, and networking, those are the topics that are emphasized in this book. Unlike many certification books, this one emphasizes a hands-on approach by using goal-oriented tasks to demonstrate Linux tools. This approach to learning about Linux makes it a useful adjunct to more traditional textbooks, such as my LPIC-1: Linux Professional Institute Certification Study Guide (Sybex, 2005) and my Linux+ Study Guide, 3rd Edition (Sybex, 2005).
