While the UNIX/Linux codebase has moved on significantly, even today, Linos' work is is a fascinating read and, in many ways, more interesting and entertaining to read than Tannenbaum's Minix textbook.
It great helpful for my understanding about Unix.
It was republished shortly after the author died when the politics of the ownership of the Unix sources settled down.
So what's so special about the book?
The first reason is that John Lions believed strongly that just as in literature, where being able to read and analyse great works is more likely to lead to being able to write comparable works, software designers should learn to read and criticise working code. He chose Unix, 6th edition, running on the PDP-11. His book is a subset of the kernel sources, with commentary.
The second reason is that the code itself is, in general, pretty fine stuff. It includes the legendary comment /* you are not expected to understand this */. It's amazing that so much of modern Unix functionality already existed in the mid-70s and ran in only 32kbytes of RAM.
And thirdly, it's a historical document that describes a real operating system, that's come to effect the development of most subsequent system software.
It's a great read, if you're a geek, and you suspect that good code, like good literature should be read and enjoyed.
