As part of their desktop reference series, Perl in a Nutshell is everything programmers have come to expect: clear, concise and no-nonsense information on the subjects which matter.
Reminiscent of the Perl man pages, the book covers a wide variety of topics from a brief (yet useful) introduction to the language through a breakdown of the standard modules, to facilities including Tcl, Sockets programming, the LWP libs and even the Win32 interface.
Supported by a heavy duty index which makes finding the right piece of information a breeze, this 650-page tome is bound to see some serious action from any Perl programmer with a busy work schedule.
The fact that it bills itself as a quick reference goes some way to showing that Perl In A Nutshell is not a compact beginners guide--if you want one of those try O'Reilly's Learning Perl. However, for the workaday programmer who needs an elbow-side reference manual or the occasional coder looking for a memory jogger, this book is worth it's weight in gold. --This text refers to an out of print or unavailable edition of this title.

For various reasons, I aleays prefered the first Programming Perl. I found it more complete and easier to find what I wanted. However the Perl 5 improvements to the language, meant a bigger book and a revision and I always have found it a little harder to find the odd things I am looking for when coding.
Now we have the "Quick Reference" Perl in a Nutshell, finding the correct syntax is easy and it covers the wider range of many of the other modules too. Together with the cookbook and the others, you have good solid, high quality upto date documentation, reference and solid working examples. In addition the books are very readable and clearly set out, which makes reading then a pleasure
The core of the book begins with a language reference. Operators, special variables, file test operators, etc (all those things you can forget if you've not used them for a bit) and available functions are listed. There might not be much here that isn't in the man pages, but it's much easier to read a book on the bus. Besides, I found that flipping through the pages I discovered lots of functions that I didn't know about before.
Then the standard modules are documented. Each one is explained briefly, and the method calls are documented. Again, there might not be much new stuff in here, but it's a very useful reference.
Next come chapters on CGI/mod_perl, Databases, Network programming, Perl/Tk and Win32. These are rather good. They don't necessarily tell you where to start, but give you concise examples of how things can be done. I've learnt loads about what you can do with Perl just by flipping through them.
Combine this with the Cookbook and the online docs, and I've got everything I need for day to day coding. And you can't knock it at this price.
