Practical, in-depth knowledge of the system programming interfaces that drive the UNIX and Linux kernelsBuilding on W. Rich Stevens’ pioneering work, this third edition of the classic was updated by Steve Rago, a colleague of Stevens, to reflect technical advances and best practices aligning with Version 4 of the Single UNIX Specification.This edition covers more than seventy interfaces including:POSIX asynchronous I/OSpin locksBarriersPOSIX semaphoresSteve carefully retains the spirit and approach that have made this book so valuable, starting with files, directories, and processes, carefully laying the groundwork for more advanced techniques, such as signal handling and terminal I/O. And he thoroughly covers threads and multithreaded programming, and socket-based IPC.Filled with examples, case-studies, and access to thousands of lines of downloadable code, Advanced Programming in the UNIX® Environment has helped generations of programmers write code with exceptional power, performance, and reliability.

O'Reilly's bestselling book on Linux's bash shell is at it again. 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 other words, it's what lets you communicate with the computer via the keyboard and display. Mastering the bash shell might sound fairly simple but it isn't. 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 shellThe basics of interactive shell use, including UNIX file and directory structures, standard I/O, and background jobsCommand line editing, history substitution, and key bindingsHow to customize your shell environment without programmingThe nuts and bolts of basic shell programming, flow control structures, command-line options and typed variablesProcess handling, from job control to processes, coroutines and subshellsDebugging techniques, such as trace and verbose modesTechniques for implementing system-wide shell customization and features related to system security Read more

If you are new to Unix, this concise book will tell you just what you need to get started and no more. Unix was one of the first operating systems written in C, a high-level programming language, and its natural portability and low price made it a popular choice among universities. Initially, two main dialects of Unix existed: one produced by AT&T known as System V, and one developed at UC Berkeley and known as BSD. In recent years, many other dialects have been created, including the highly popular Linux operating system and the new Mac OS X (a derivative of BSD). Learning the Unix Operating System is a handy book for someone just starting with Unix or Linux, and it's an ideal primer for Mac and PC users of the Internet who need to know a little about Unix on the systems they visit. The fifth edition is the most effective introduction to Unix in print, covering Internet usage for email, file transfers, web browsing, and many major and minor updates to help the reader navigate the ever-expanding capabilities of the operating system: In response to the popularity of Linux, the book now focuses on the popular bash shell preferred by most Linux users. Since the release of the fourth edition, the Internet and its many functions has become part of most computer user's lives. A new chapter explains how to use ftp, pine for mail, and offers useful knowledge on how to surf the web. Today everyone is concerned about security. With this in mind, the author has included tips throughout the text on security basics, especially in the Internet and networking sections. The book includes a completely updated quick reference card to make it easier for the reader to access the key functions of the command line. Read more
