Apart from Kernighan and Ritchie's "The "C" Programming Language", a recommended text, was "A Practical Guide to UNIX System V" by Mark and Sobell.. I assume that Linux is sufficiently close to UNIX, to use similar principles, such as pre-emptive multitasking and forks and killing children, etc, and, when I started learning about UNIX, in terms of the operating principles, from memory, books about operating systems, such as Operating Systems - Design and Implementation - by Tanenbaum Operating System Concepts - by Silberschatz The first of the two, was a red book, from memory, published, I think, by Prentice Hall, and it related to the development of Minix, which was the forerunner to Linux, and, I believe that Linus Torvalds developed Linux, as an expansion of Minix and possibly started with that book, or something like it (I stand to be corrected, on in this belief). These books are from 20-30 years ago, in the learning of operating systems and UNIX; in the design and implementation. The question is, what is the nature of the understanding that you want of Linux? Is it the interaction between the layers, for example, the HAL and the higher layers; is it the multitasking; is it understanding administration (such as, do not do one of the whoopsies - using "chmod .", as one (other) student did, when I was learning UNIX), is it scripting and shell processing, or, is it the "design and implementation" of the operating system, and, in that, does what you want, include comparative design and implementation of operating systems? I am no expert (my knowledge is quite limited) in the intricacies of the Linux operating system, but, many books exist, about various aspects of operating systems, including the UNIX-based operating systems -- Bret Busby Armadale West Australia ..............
