4.0 out of 5 stars Surprised me, March 2, 2004
I often take a dim view of books that use superlatives in their titles. I also don't think there is anything "wicked cool" about shell scripting in general: if you need anything complex at all, Perl or something else is probably a much better way to to it. Shell scripting gets awfully nasty awfully fast.

However, I was wrong. Yes, shell scripting is an abominable way to approach most of the tasks this book explores. Just the same, the author does it "wicked cool" and you can learn a lot both from how he sees the problem and the other Unix tools he uses as part of the script. So while you might shudder at the idea of writing a link-checker in Bash, the author's clever use of Lynx's "traverse" flag is something you might make use of elsewhere. You'll find useful things like that throughout the book, and even if you'd rather write it in Perl or whatever, the logic is worth examining.

Mac OS X users will appreciate that a whole chapter is devoted to that. There's nothing particularly deep there, nothing you will be surprised by, but it's nice to see Mac get specific mention. That brings up another important point: shells are different and Unixes are different. The author does pay a lot of attention to the differences that can cause problems for your scripts when they need to run on different platforms.

4.0 out of 5 stars Try Scripting Web Applications, March 2, 2004
By W Boudville (Terra, Sol 3) - See all my reviews
(TOP 10 REVIEWER)    (REAL NAME)      
The book is aimed at all users and systems administrators of linux and every unix variant, including most importantly the MacOS. If you already know some scripting, you should be quite at ease here. Taylor does decide to restrict his discussion to the Bourne shell and its descendent, bash. He drops the C shell! But, as he points out, the scripts he gives can be easily rewritten in the latter if you desire.

The book can be roughly divided into two parts. The first is essentially traditional scripting tasks. A user from 1988 would see original material here, but no qualitative surprises.

The second half of the book is more interesting. It centres on Web applications. For example, when running a Web server that uses CGI, Perl and C are often the choice for implementing logic. But sometimes you can get by with a simpler approach - using a Bourne shell. Taylor shows how to do this to make simple web pages, with images, even. Cool! Though this outlook lacks the full expressive power of generating dynamic pages via Java Server Pages/Servlets, these latter alternatives can be quite forbidding to learn. If you are already comfortable with sed, awk, grep [etc], you may want to try this approach, provided your web site is not too complex.

In summary, the web scripting approach suggested here may be the most distinctive and useful sections. Worth checking out.

2.0 out of 5 stars Lots of unnecessary material, and what's good is already available out there, March 2, 2006
WICKED COOL SHELL SCRIPTS is a collection of pre-made bash scripts for various tasks similar to one of O'Reilly's "cookbooks". All scripts here use bash--the author rejects csh because of Tom Christiansen's classic essay "Csh Programming Considered Harmful" and the Korn shell because he considers it fine for interactive use but not so good for scripting.

The basic format of each entry is first the problem--what the user wants to do--then the code, followed sometimes by an explanation and advice on hacking the code. The book is not really an introduction to Bash scripting. If you want a systematic primer I'd recommend O'Reilly's LEARNING THE BASH SHELL or any of a dozen libre tutorials.

Some of the scripts are useful and solve problems I've occasionally faced. For example, the GNU units program can't do temperature conversions, but a script is given here which uses bc to provide a solution. Quite elegant is a script with which the user can find the time anywhere in the world by querying in a friendly manner the system's zoneinfo files. In spite of some neat gimmicks, however, I don't think I can really recommend the book unless you're someone about to take a voyage on the south seas and won't have Internet access. Many of these scripts can be found on the Web, and far too many scripts here solve problems already long solved by available programs. The author describes a secure version of locate, when slocate is already easily installable on most *nix systems. A script for rotating log files is done when metalog and other common log programs do this automatically. Take out all these unnecessary scripts, and the amount of useful content in the book turns out to be very low indeed.
