Reddit reviews UNIX Internals: The New Frontiers

Mostly when he talks about the process/thread implementation and the process memory working set and page replacement algorithms. Also when he talks about the Unix security model (user|group|all). It is now a bit more elaborated than that, and you can use ACLs almost like in Windows. And at one point he asks when was the last time someone used pipes (|) for composing programs!

I would recommend this book, UNIX Internals: The New Frontiers, that explains the internal implementation of a variety of Unix systems in the mid nineties. Amazon says that a new edition is planned for January next year, good news!

The closest thing I can think of is Uresh Vahalia's book "UNIX Internals". It's more technical than Code, but it's really quite well written and clear. It's somewhat hard to find, though.

I'm surprised this one hasn't been mentioned yet; it's arguably one of the best book on UNIX operating systems design. It gives a lot of valuable information on how to efficiently implement SMP kernels which is something missing from a lot of other books. Maybe not adequate if you're a complete beginner though.
