Title: Perl 5 Desktop Reference
Author: Johan Vromans
Publisher: O'Reilly & Associates, Inc.

Being one of the smallest books about Perl, this book is not intended as a teaching guide but as a reference manual to the idiosyncracies of the Perl language itself. I feel that once you learn Perl, it won't hurt you to review this book every so often (especially special variables and function names) to make sure that you are aware of their existance.

Since most developers have a favorite way to do things and tend not to change what works, by reviewing other possibilities of the Perl language, on an ongoing basis, should help you to enhance your skillset. Personally, I found a solution to an odd problem relating to $ARGV that I had not encountered before, on page 22 of the Perl 5 Desktop Reference. Many of the larger books I have read never detailed the specific behavior of the @ARGV array and how it relates to line input operator (<>).

I noticed a few items missing from this reference handbook:

  • # - comment character
  • #! - first line Perl switches
  • << - used with verbatim string storage or output
  • $a, $b special variables used in sorting
  • $| autoflush flag

    Since several blank pages are provided in the back of this handbook, these missing items can be easily added.

    If you consider yourself a Perl developer or want to become one, I highly recommend having the Perl 5 Desktop Reference close at hand.
