How Linux Works, 3rd Edition: What Every Superuser Should Know • 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
More.
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. Brian Ward has been working with Linux since 1993.
What’s new in how Linux works?
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.
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.
Is Linux a GNU system?
“Linux is a GNU system and the DWARF support”. Newsgroup : comp., and os., and linux., and misc. RMS’s idea (which I have heard first-hand) is that Linux systems should be considered GNU systems with Linux as the kernel.
What is gnu linux?
GNU/Linux is an operating system, a large piece of software that manages a computer. It is similar to Microsoft Windows, but it is entirely free. The accurate name is GNU/Linux but “Linux” is used more often.
A inquiry we ran across in our research was “What is the GNU/Linux project?”.
The GNU Project supports GNU/Linux systems as well as the GNU system. The FSF funded the rewriting of the Linux-related extensions to the GNU C library, so that now they are well integrated, and the newest GNU/Linux systems use the current library release with no changes. The FSF also funded an early stage of the development of Debian GNU/Linux.
Variants of the GNU operating system, which use the kernel Linux, are now widely used; though these systems are often referred to as “Linux”, they are more accurately called “GNU/Linux systems“.
One idea is that gNU is a recursive acronym for “GNU’s Not Unix!“, chosen because GNU’s design is Unix-like, but differs from Unix by being free software and containing no Unix code. The GNU project includes an operating system kernel, GNU HURD, which was the original focus of the Free Software Foundation (FSF).
