This book is designed to help you prepare for the Linux Professional Institute Certification Level 1 exams 101 and 102. The Linux Professional Institute is a distribution-independent, nonprofit organization. The exams are developed to certify an individual’s expertise with Linux systems. Level 1 certification is based upon many general tasks involving Linux systems. This book provides all the information you need to perform these tasks. Because of this, the book is useful as a study guide as well as a general Linux reference. We believe that this book will prove to be a useful tool when preparing for the LPIC exams and that you will want to keep it nearby as a handy resource while working with Linux systems. How This Book Is Organized This book is organized into four major parts, followed by several appendixes, a robust glossary, an index, and a compact disc. Here’s what you’ll find in this book: Part I: Installing Linux and Getting Started Part I presents basic information about Linux. It covers the basic installation and configuration of the Linux operating system. This part introduces the shell environ- ment and its usage. Finally, this part covers software installation, including the packaging systems used on Debian and Red Hat distributions. Part II: Getting Around in Linux Part II covers the basics of using Linux. This part explains many of the text process- ing tools available for Linux. Information on working with Linux partitions and file systems is also covered in this section. Another task required to get around in Linux is managing files and directories. This part introduces the commands most often used for this task. The documentation resources available to aid with the proper use of these commands and many of the tasks required on Linux are also covered here. Part II also explores the boot process, detailing the use of various configuration files and run levels. Finally, this part explores XFree86, the graphical user interface available for Linux. 4772-0 FM.F 5/14/01 4:20 PM Page ix [...]... 16 1 16 1 16 4 16 5 16 6 16 7 16 7 17 0 17 1 17 2 17 3 17 5 17 6 17 6 17 7 17 9 18 0 18 1 18 2 18 3 18 3 xxiii 4772-0 FM.F xxiv 5 /14 / 01 4:20 PM Page xxiv LPIC 1 Certification Bible Using the stream editor Using grep Enhancing Searches with Regular Expressions Assessment...
