I have read other books related to UNIX internels but this is the first one specific to HP-UX. The auther has done the job very well. It was interesting to see internal data structures. I would recommend this book for people who want to understand HP-UX in depth.
Very detailed, excellent presentation
Rating: 5/5
This is a very thorough, well-presented text covering the "guts" of HP-UX. It is packed with excellent diagrams, kernel structures, syscall details, and pretty much everything "under the hood." All this is presented clearly: sufficient high-level overview to provide the "big picture", followed up with the very fine details. adb and q4 are used throughout, along with many illustrative examples and sample output.
