Anyone who's done programming work knows that you spend half your coding time looking for other people's solutions to the problems you're facing in your project. Particularly when you're dealing with times, dates, standard calculations, and other common problems, you find yourself saying, "Someone must have solved this before." And, indeed, someone usually has. Linux Programming by Example is a dense compendium of Linux software solutions--tools, algorithms, and procedures that solve data-processing challenges of the sort that crop up in all sorts of software projects. Though it does not address X11 user-interface programming or network communications much, this book does a great job of communicating recommended practices for command-line interfaces, filesystem manipulation, internationalization and localization, and inter-process communications. Taken together with The Art of Unix Programming, this book will help you solve difficult Linux programming problems quickly.
 Unlike a lot of code-oriented books, this one manages to keep its samples concise, and devote more space to discussions of why things are done than to the code that actually does them. This promotes understanding: You can always mess around with the code yourself on your own. Overall, Arnold Robbins does an excellent job of stripping away some of the hacker mystique to reveal the code behind the curtain. This book shows how to work Linux magic. --David Wall
 Topics covered: Linux programming in C, mostly at a level concerned with user input from the command line, file I/O, interprocess signalling, and memory management.

Effective awk Programming,3rd Edition, focuses entirely onawk, exploring it in the greatest depth of the three awk titles we carry. It's an excellent companion piece to the more broadly focused second edition.This book provides complete coverage of the gawk 3.1 language as well as the most up-to-date coverage of the POSIX standard forawk available anywhere. Author Arnold Robbins clearly distinguishes standard awk features from GNU awk(gawk)-specific features, shines light into many of the "dark corners" of the language (areas to watch out for when programming), and devotes two full chapters to example programs. A brand new chapter is devoted to TCP/IP networking with gawk. He includes a summary of how the awk language evolved.The book also covers:
<ul>
<li>Internationalization of gawk
</li>
<li>Interfacing to i18n at the awk level</li>
<li>Two-way pipes</li>
<li>TCP/IP networking via the two-way pipe interface</li>
<li>The new PROCINFO array, which provides information about running gawk
</li>
<li>Profiling and pretty-printing awk programs</li>
</ul>In addition to covering the awk language, this book serves as the official "User's Guide" for the GNU implementation of awk (gawk), describing in an integrated fashion the extensions available to the System V Release 4 version of awk that are also available in gawk.As the official gawk User's Guide, this book will also be available electronically, and can be freely copied and distributed under the terms of the Free Software Foundation's Free Documentation License (FDL). A portion of the proceeds from sales of this book will go to the Free Software Foundation to support further development of free and open source software.The third edition of Effective awk Programming is a GNU Manual and is published by O'Reilly &amp; Associates under the Free Software Foundation's Free Documentation License (FDL). A portion of the proceeds from the sale of this book is donated to the Free Software Foundation to further development of GNU software. This book is also available in electronic form; you have the freedom to modify this GNU Manual, like GNU software. Copies published by the Free Software Foundation raise funds for GNU development.

The Korn shell is an interactive command and scripting language for accessing Unix and other computer systems. As a complete and high-level programming language in itself, it's been a favorite since it was developed in the mid 1980s by David G. Korn at At &amp; T Bell Laboratories. Knowing how to use it is an essential skill for serious Unix users. Learning the Korn Shell shows you how to use the Korn shell as a user interface and as a programming environment. Writing applications is often easier and quicker with Korn than with other high-level languages. Because of this, the Korn shell is the most often used shell in commercial environments and among inexperienced users. There are two other widely used shells, the Bourne shell and the C shell. The Korn shell, or ksh, has the best features of both, plus many new features of its own. ksh can do much to enhance productivity and the quality of a user's work, both in interacting with the system, and in programming. The new version, ksh93, has the functionality of other scripting languages such as awk, icon, Perl, rexx, and tcl. Learning the Korn Shell is the key to gaining control of the Korn shell and becoming adept at using it as an interactive command and scripting language. Prior programming experience is not required in order to understand the chapters on basic shell programming. Readers will learn how to write many applications more easily and quickly than with other high-level languages. In addition, readers will also learn about Unix utilities and the way the Unix operating system works in general. The authors maintain that you shouldn't have to be an internals expert to use and program the shell effectively. The second edition covers all the features of the current version of the Korn shell, including many new features not in earlier versions of ksh93, making it the most up-to-date reference available on the Korn shell. It compares the current version of the Korn

For people who create and modify text files, sed and awk are power tools for editing. sed, awk, and regular expressions allow programmers and system administrators to automate editing tasks that need to be performed on one or more files, to simplify the task of performing the same edits on multiple files, and to write conversion programs. The sed &amp; awk Pocket Reference is a companion volume to sed &amp; awk, Second Edition, Unix in a Nutshell, Third Edition, and Effective awk Programming, Third Edition. This new edition has expanded coverage of gawk (Gnu awk), and includes sections on: An overview of sed and awk's command line syntax Alphabetical summaries of commands, including nawk and gawk Profiling with pgawk Coprocesses and sockets with gawk Internationalization with gawk A listing of resources for sed and awk users This small book is a handy reference guide to the information presented in the larger volumes. It presents a concise summary of regular expressions and pattern matching, and summaries of sed and awk. Arnold Robbins, an Atlanta native now happily living in Israel, is a professional programmer and technical author and coauthor of various O'Reilly Unix titles. He has been working with Unix systems since 1980, and currently maintains gawk and its documentation.

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.

Many Linux and Unix developers are familiar with the Gnu debugger (Gbd), the invaluable open source tool for testing, fixing, and retesting software. And since Gdb can be ported to Windows, Microsoft developers and others who use this platform can also take advantage of this amazing free software that allows you to see exactly what's going on inside of a program as it's executing. This new pocket guide gives you a convenient quick reference for using the debugger with several different programming languages, including C, C++, Java, Fortran and Assembly. The Gnu debugger is the most useful tool during the testing phase of the software development cycle because it helps you catch bugs in the act. You can see what a program was doing at the moment it crashed, and then readily pinpoint and correct problem code. With the Gdb Pocket Reference on hand, the process is quick and painless. The book covers the essentials of using Gbd is a testing environment, including how to specify a target for debugging and how to make a program stop on specified conditions. This handy guide also provides details on using the debugger to examine the stack, source files and data to find the cause of program failure-and then explains ways to use Gbd to make quick changes to the program for further testing and debugging. The ability to spot a bug in real time with Gdb can save you hours of frustration, and having a quick way to refer to Gbd's essential functions is key to making the process work. Once you get your hands on the Gdb Pocket Reference, you'll never let go!
