In order to thoroughly understand what makes Linux tick and why it works so well on a wide variety of systems, you need to delve deep into the heart of the kernel. The kernel handles all interactions between the CPU and the external world, and determines which programs will share processor time, in what order. It manages limited memory so well that hundreds of processes can share the system efficiently, and expertly organizes data transfers so that the CPU isn't kept waiting any longer than necessary for the relatively slow disks. The third edition of Understanding the Linux Kernel takes you on a guided tour of the most significant data structures, algorithms, and programming tricks used in the kernel. Probing beyond superficial features, the authors offer valuable insights to people who want to know how things really work inside their machine. Important Intel-specific features are discussed. Relevant segments of code are dissected line by line. But the book covers more than just the functioning of the code; it explains the theoretical underpinnings of why Linux does things the way it does. This edition of the book covers Version 2.6 , which has seen significant changes to nearly every kernel subsystem, particularly in the areas of memory management and block devices. The book focuses on the following topics: * Memory management, including file buffering, process swapping, and Direct memory Access (DMA) * The Virtual Filesystem layer and the Second and Third Extended Filesystems * Process creation and scheduling * Signals, interrupts, and the essential interfaces to device drivers * Timing * Synchronization within the kernel * Interprocess Communication (IPC) * Program execution Understanding the Linux Kernel will acquaint you with all the inner workings of Linux, but it's more than just an academic exercise. You'll learn what conditions bring out Linux's best performance, and you'll see how it meets the challenge of providing good system response during process scheduling, file access, and memory management in a wide variety of environments. This book will help you make the most of your Linux system.

Writing better software: 30 years of UNIX development wisdom In this book, five years in the making, the author encapsulates three decades of unwritten, hard-won software engineering wisdom. Raymond brings together for the first time the philosophy, design patterns, tools, culture, and traditions that make UNIX home to the world's best and most innovative software, and shows how these are carried forward in Linux and today's open-source movement. Using examples from leading open-source projects, he shows UNIX and Linux programmers how to apply this wisdom in building software that's more elegant, more portable, more reusable, and longer-lived.

Unlike some operating systems, Linux doesn't try to hide the important bits from you—it gives you full control of your computer. But to truly master Linux, you need to understand its internals, like how the system boots, how networking works, and what the kernel actually does.
In this completely revised second edition of the perennial best seller How Linux Works, author Brian Ward makes the concepts behind Linux internals accessible to anyone curious about the inner workings of the operating system. Inside, you'll find the kind of knowledge that normally comes from years of experience doing things the hard way. You'll learn:
How Linux boots, from boot loaders to init implementations (systemd, Upstart, and System V)
* How the kernel manages devices, device drivers, and processes
* How networking, interfaces, firewalls, and servers work
* How development tools work and relate to shared libraries
* How to write effective shell scripts
You'll also explore the kernel and examine key system tasks inside user space, including system calls, input and output, and filesystems. With its combination of background, theory, real-world examples, and patient explanations, How Linux Works will teach you what you need to know to solve pesky problems and take control of your operating system.

Fun and functional Linux, Mac OS X and UNIX shell scripts The UNIX shell is the main scripting environment of every Linux, Mac OS X and UNIX system, whether a rescued laptop or a million-dollar mainframe. This cookbook of useful, customizable, and fun scripts gives you the tools to solve common Linux, Mac OS X and UNIX problems and personalize your computing environment. Among the more than 100 scripts included are an interactive calculator, a spell checker, a disk backup utility, a weather tracker, and a web logfile analysis tool. The book also teaches you how to write your own sophisticated shell scripts by explaining the syntax and techniques used to build each example scripts. Examples are written in Bourne Shell (sh) syntax.

This is the story of Linus Torvalds, the maverick Finnish computer genius who invented the powerful LINUX operating system. As well as being free, LINUX is more powerful and stable than anything that Microsoft can offer, thus making Torvalds Bill Gates' number one enemy. Today, LINUX is exploding on to the market, and its creator is household. Linus Torvalds is already a folk hero within the technolgy world, often mobbed at trade shows and forever asked to give interviews by the media. But Torvalds is a most unlikely celebrity: a family man, he lives in a cramped house in Santa Clara with his wife, Tove, a Finnish karate champion, and their two daughters. He claims to this day that he invented LINUX "just for fun". --This text refers to an out of print or unavailable edition of this title.

The Linux Command Line takes you from your very first terminal keystrokes to writing full programs in Bash, the most popular Linux shell (or command line). Along the way you'll learn the timeless skills handed down by generations of experienced, mouse-shunning gurus: file navigation, environment configuration, command chaining, pattern matching with regular expressions, and more.
In addition to that practical knowledge, author William Shotts reveals the philosophy behind these tools and the rich heritage that your desktop Linux machine has inherited from Unix supercomputers of yore.
As you make your way through the book's short, easily-digestible chapters, you'll learn how to:
* Create and delete files, directories, and symlinks
* Administer your system, including networking, package installation, and process management
* Use standard input and output, redirection, and pipelines
* Edit files with Vi, the world's most popular text editor
* Write shell scripts to automate common or boring tasks
* Slice and dice text files with cut, paste, grep, patch, and sed
Once you overcome your initial "shell shock," you'll find that the command line is a natural and expressive way to communicate with your computer. Just don't be surprised if your mouse starts to gather dust.
