As with the other comments here, I am disappointed not to find an updated version. I have owned this book since shortly after it was first published, and it has proven invaluable on many occasions. However, I came here looking for an update, as it is no longer so relevant to modern revisions of the UNIX system.

I have a reasonable library of books here and a large majority are O'Reilly titles, for which I have the utmost respect. I have to say that I feel slightly let down on this occasion :-(
