Introduction
Why should you learn about Linux? It’s a fast-growing operating system, and it is 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’re looking for a new job or you’re looking for a promotion. For instance, this knowledge will help you make an informed decision about if and when you should deploy Linux.
The Linux Professional Institute (LPI) has developed its LPIC-1 certification as an introductory for people who want to enter careers involving Linux. The exam is meant to certify that an individual has the skills necessary to install, operate, and troubleshoot a Linux system and is familiar with Linux-specific concepts and basic hardware.
The purpose of this book is to help you pass the LPIC-1 exams (101 and 102) updated in 2012. Because these exams cover basic Linux installation, configuration, maintenance, applications, networking, and security, those are the topics that are emphasized in this book. You’ll learn enough to get a Linux system up and running and to configure it for many common tasks. Even after you’ve taken and passed the LPIC-1 exams, this book should remain a useful reference.
