This not a book for those learning HP-UX and so some content is misplaced in a book of this type. Including MAN pages instead of a more reader friendly interpretation is not good. However if you need know something it is reasonably easy to find and gets to the point. This is a reference book, which is what I wanted and I got it. If you don't really know HP-UX then you won't like this book.
This is really a summary of Solaris Administration. There needs to be more detail and more subject area's covered. Some of the basic info is missing or very hard to find. It is not badly written so perhaps the next edition will be less rushed.
