Brian Ward

what every superuser should know

In this completely revised second edition, Brian Ward makes accessible the concepts behind Linux internals to anyone curious about the inner workings of the operating system. Readers will 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. Readers also will explore the kernel and examine key system tasks inside user space, including system calls, input and output, and filesystems. --, Edited summary from book
