Contents is slightly outdated and covers only ksh88. Still the first edition is somewhat better then the second that was upgraded by a different author. The key factor for this book is the right definition of intended audience: it is really the best introductory book for students at the university level and professionals. Reader needs to know some Unix (and the reader is expected to know classic Unix utilities) or programming experience.
Actually it is one of the few shell books that provides a good coverage of
usage of pipes in shell scripting, the quintessential feature of the Unix shell.
This is the strongest feature of the book. At the same time the books also contains
a lot of subtle but important information for example it explains why an alias
ll='ls -la ' (with trailing space) is more useful then without trailing
space. It also covers "IFS" variable, shell functions. In several chapter
the authors develop the example of a simple, yes (marginally) useful tool: an
analog of C-shell popd/pushd/dirs troika for the ksh. the last chapters contains
an example of a really complex (shell debugger) script.
Paradoxically the first edition is considered to be weak by some Amazon.com
readers: IMHO this is a nice demonstration of an "Amazon lemmings effect". May
be the reason is that the book is too complex to be the first book for learning
shell, if you are complete novice (often shell course introduces people to Unix
at universities). In such cases
A Practical Guide
to Solaris might be a better bet, but still I recommend to buy this book
as a second book -- it contains a lot of important information that helps better
understand shell and write better shell scripts. The second edition should
be available in April 2002, and with 9 years and 40 pages we can expect a lot
of improvements ;-)
Shortcomings of the book include very superficial treatment of .profile and
.kshrc files. Some examples also can be made batter (I think that pushd/popd
example that authors use can be replaced by something more useful) but that
can be said almost about any book. Neither sed not awk is covered (O'Reilly
has a separate book on this subject). At the same time the fact that book does
not use awk cripple some examples as it solves several shell problems
more elegantly than other built-in UNIX commands.
