Linux for the Superuser
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 third edition of the bestselling How Linux Works, author Brian Ward peels back the layers of this well-loved operating system to make Linux internals accessible. This edition has been thoroughly updated and expanded with added coverage of Logical Volume Manager (LVM), virtualization, and containers.
You'll learn:
- How Linux boots, from boot loaders to init (systemd)
- 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 processes, including system calls, input and output, and filesystem maintenance. With its combination of background, theory, real-world examples, and thorough explanations, How Linux Works, 3rd Edition will teach you what you need to know to take control of your operating system.
NEW TO THIS EDITION:
- Hands-on coverage of the LVM, journald logging system, and IPv6
- Additional chapter on virtualization, featuring containers and cgroups
- Expanded discussion of systemd
Covers systemd-based installations
