Professional PERL Programming

By Simon Cozens,Arthur Corliss et al.
I read this book last month. For those looking to develope serious applications, improve productivity, or learn a more portable replacement for shell scripts, this book provides in-depth guide. First few chapters are devoted to basic concepts like scalars,Operators and structure ,flow and control in PERL programs. The chapter on Perl modules covers loading code into our scripts using do,require and use and differences between them. Pragmatic modules and how they work,the special varaibles %INC and @INC and how to manipulate them, finding out which modules are installed, postponing module loading until their use etc. There is chapter on perl's regular expressions and how to write them efficiently. There is good coverage on input and output with FileHandles,manipulating files and directories and text processing. There is good information on creating and managing processes and networking with perl and command line processing using perl. Object oriented Perl is also covered in the book.
