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.
How Linux boots, from boot loaders to init (systemd)How the kernel manages devices, device drivers, and processesHow networking, interfaces, firewalls, and servers workHow development tools work and relate to shared librariesHow 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 IPv6Additional chapter on virtualization, featuring containers and cgroupsExpanded discussion of systemd
Covers systemd-based installations
Lee Teschler, Microcontroller Tips
"The book is very thorough from looking down into the hardware, through delving into how the kernel functions, to covering the most important commands, file systems, swap space, boot loaders, networking and more. In fact, I'm not at all surprised that this book has survived to its 3rd edition both because it's a genuinely good book and because Linux has gone through some serious changes in the past seven years, especially related to such things as its use of containers, the flexibility of logical volume manager and the continued move toward virtualization. . . . This is a very thorough and up-to-date book. After using Unix and then Linux for nearly 40 years, I am still getting a lot of value and significant insights from reading it."
Sandra Henry-Stocker, longstanding Linux journalist

Everyday Linux User
You ll get an essential understanding of what s going on under the hood without getting bogged down in minutiae making this a very refreshing (and wholly recommended) addition to the Linux literature.
Phil Bull, co-author of Ubuntu Made Easy and member of the Ubuntu documentation team
Dives straight into the transparent depths of Linux-based operating systems and shows us how all the pieces fit together.
Earns its place on the shelf as an essential reference.
