Praise for the First Edition: "This outstanding book ... gives the reader robust concepts and implementable knowledge of this environment. Graphical user interface (GUI)-based users and developers do not get short shrift, despite the command-line interface's (CLI) full-power treatment. ... Every programmer should read the introduction's Unix/Linux philosophy section. ... This authoritative and exceptionally well-constructed book has my highest recommendation. It will repay careful and recursive study." --Computing Reviews, August 2011 Mastering Modern Linux, Second Edition retains much of the good material from the previous edition, with extensive updates and new topics added. The book provides a comprehensive and up-to-date guide to Linux concepts, usage, and programming. The text helps the reader master Linux with a well-selected set of topics, and encourages hands-on practice. The first part of the textbook covers interactive use of Linux via the Graphical User Interface (GUI) and the Command-Line Interface (CLI), including comprehensive treatment of the Gnome desktop and the Bash Shell. Using different apps, commands and filters, building pipelines, and matching patterns with regular expressions are major focuses. Next comes Bash scripting, file system structure, organization, and usage. The following chapters present networking, the Internet and the Web, data encryption, basic system admin, as well as Web hosting. The Linux Apache MySQL/MariaDB PHP (LAMP) Web hosting combination is also presented in depth. In the last part of the book, attention is turned to C-level programming. Topics covered include the C compiler, preprocessor, debugger, I/O, file manipulation, process control, inter-process communication, and networking. The book includes many examples and complete programs ready to download and run. A summary and exercises of varying degrees of difficulty can be found at the end of each chapter. A companion website (http://mml.sofpower.com) provides appendices, information updates, an example code package, and other resources for instructors, as well as students.

Look beyond the basics of Mac programming and development to become a Mac power user. When most people think about the Mac, they think about the amazing graphical user interface macOS is known for. However, there is a whole world to explore beneath the hood. This book approaches working directly in the terminal with fun projects and ideas to help turn you into an advanced Mac user. You'll work with Brew (HomeBrew), which gives you the ability to install applications from Linux (and Unix) that can make the terminal more useful. This is important, because a lot of applications have been stripped out of macOS or deprecated. For example, Apple's built-in PHP is usually a major release behind. You'll also customize your terminal to change everything about it, making it your own. The whole world is about personalizing. Why put up with the Apple defaults? Once you have your terminal set up and ready to rock, you'll review the basics of programming on the Mac terminal. This will allow you to get a taste of power scripting. You'll discover the power of bash, PHP, and Python. And then you'll apply those tools to web development. Tweak Your Mac Terminal takes you on a journey into a world of the terminal and its hidden applications. What You'll Learn Customize the terminal to make it perfect for your needs Develop web applications using basic coding skills in the terminal Install HomeBrew and by extension Linux and Unix applications Who This Book Is ForMac users who are already very familiar with the GUI and want to go further. This book will especially help starting IT professionals and beginning programmers.

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.
