Best-selling guide to the inner workings of the Linux operating system
with over 50,000 copies sold since its original release in 2014.
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.**
