Linux for the Superuser

Linux is an operating system that gives the user full control of their computer and doesn’t hide important bits away like some other operating systems. However, to truly master Linux, it is important to understand its internal workings, including how it boots, how networking functions, and how the kernel operates. In How Linux Works, 3rd Edition, author Brian Ward delves deep into the layers of this popular operating system, making Linux internals accessible to all. This updated edition includes added coverage on Logical Volume Manager (LVM), virtualization, and containers.

The book covers the following topics:
– 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
– A closer look at the kernel and key system tasks inside user-space processes, including system calls, input and output, and filesystem maintenance.

With a mix of background, real-world examples, theory, and thorough explanations, How Linux Works, 3rd Edition teaches readers what they need to know to fully understand and control their operating system.

NEW TO THIS EDITION:
– In-depth 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
