How Linux Works: What Every Superuser Should Know, 2nd Edition

Book Description

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.

书名：How Linux Works: What Every Superuser Should Know, 2nd Edition

与一些操作系统不同，Linux不会试图对你隐藏重要的部分–它让你完全控制你的计算机。但要真正掌握Linux，您需要了解它的内部结构，比如系统如何引导、网络如何工作以及内核的实际功能。

在这本经过全面修订的常年畅销书第二版中 How Linux Works，作者Brian Ward使任何对操作系统内部工作方式感兴趣的人都可以接触到Linux内部机制背后的概念。在里面，你会发现通常来自多年艰苦工作经验的那种知识。你将会学到：

• Linux如何从引导加载程序引导到init实现(系统D、UpStart和System V)
• 内核如何管理设备、设备驱动程序和进程
• How networking, interfaces, firewalls, and servers work
• How development tools work and relate to shared libraries
• 如何编写有效的外壳脚本

您还将探索内核并检查用户空间中的关键系统任务，包括系统调用、输入和输出以及文件系统。它结合了背景、理论、现实世界的例子和耐心的解释， How Linux Works 将教你解决烦人的问题和控制你的操作系统所需的知识。
