Now that Linux is an established player both as a server and on the desktop Learning the bash Shell has been updated and refreshed to account for all the latest changes. Indeed, this third edition serves as the most valuable guide yet to the bash shell.As any good programmer knows, the first thing users of the Linux operating system come face to face with is the shell the UNIX term for a user interface to the system.

In truth, there are many complexities that need careful explanation, which is just what Learning the bash Shell provides.If you are new to shell programming, the book provides an excellent introduction, covering everything from the most basic to the most advanced features. And if you've been writing shell scripts for years, it offers a great way to find out what the new shell offers. Learning the bash Shell is also full of practical examples of shell commands and programs that will make everyday use of Linux that much easier. With this book, programmers will learn: How to install bash as your login shell The basics of interactive shell use, including UNIX file and directory structures, standard I/O, and background jobs Command line editing, history substitution, and key bindings How to customize your shell environment without programming The nuts and bolts of basic shell programming, flow control structures, command-line options and typed variables Process handling, from job control to processes, coroutines and subshells Debugging techniques, such as trace and verbose modes Techniques for implementing system-wide shell customization and features related to system security

Over the last few years, Linux has grown both as an operating system and a tool for personal and business use. Simultaneously becoming more user friendly and more powerful as a back-end system, Linux has achieved new plateaus: the newer filesystems have solidified, new commands and tools have appeared and become standard, and the desktop--including new desktop environments--have proved to be viable, stable, and readily accessible to even those who don't consider themselves computer gurus. Whether you're using Linux for personal software projects, for a small office or home office (often termed the SOHO environment), to provide services to a small group of colleagues, or to administer a site responsible for millions of email and web connections each day, you need quick access to information on a wide range of tools. This book covers all aspects of administering and making effective use of Linux systems. Among its topics are booting, package management, and revision control. But foremost in Linux in a Nutshell are the utilities and commands that make Linux one of the most powerful and flexible systems available. Now in its fifth edition, Linux in a Nutshell brings users up-to-date with the current state of Linux. Considered by many to be the most complete and authoritative command reference for Linux available, the book covers all substantial user, programming, administration, and networking commands for the most common Linux distributions. Comprehensive but concise, the fifth edition has been updated to cover new features of major Linux distributions. Configuration information for the rapidly growing commercial network services and community update services is one of the subjects covered for the first time. But that's just the beginning. The book covers editors, shells, and LILO and GRUB boot options. There's also coverage of Apache, Samba, Postfix, sendmail, CVS, Subversion, Emacs, vi, sed, gawk, and much more. Everything that system administrators, developers, and power users need to know about Linux is referenced here, and they will turn to this book again and again.

The Linux Professional Institute (LPI) is the leader in obtaining the independent, vendor-neutral certification that provides proof of the necessary skills in demand by IT departments. LPI Linux Certification in a Nutshell is written with the LPI exams in mind by including information on the required Topics and Objectives. Beyond preparing to pass the LPIC Level 1 exams, this book provides an excellent understanding of Linux concepts and functions. LPI Linux Certification in a Nutshell prepares system administrators for both of the General Linux LPIC Level 1 exams (101 and 102). The book is divided into two parts (one for each of the LPIC Level 1 exams), and each part features a summary of the exam, a Highlighter's Index, labs, suggested exercises, and practice exams. Part 1 covers Exam 101: GNU and Unix commands; devices, Linux filesystems, and the filesystem hierarchy standard; boot, initialization, shutdown, and run levels; documentation; and administrative tasks. Part 2 covers Exam 102: hardware and architecture; Linux installation and package management; the Linux kernel; text editing, processing, and printing; shells, scripting, programming, and compiling; the X Window System; networking fundamentals; network services; and security. While this book is designed to help system administrators prepare for the LPI certification exams, the tutorial-style approach will help newbies learn more about their Linux system. For those preparing to take the LPI certification exams, this book will prove to be invaluable in its scope and breadth.
