Combining the best features of C, UNIX utilities, and regular expressions, Perl has grown as one of the most powerful and popular scripting languages. The valuable Perl is often used for system administration, text processing and Web programming. It is even being used for more exotic areas, like bioinformatics. Perl is supported by all of the most prominent operating systems, including Windows, Unix, OS/2, Amiga, and others.

Pro Perl Debugging steps in to help resolve the dilemma of application testing and debugging—one of the biggest time commitments in a programmers daily routine. What this book will do is rescue you from substandard application testing practices. The book commences with several chapters that overview the debuggers basic features, then covers common debugging scenarios. The concluding portion examines debugger customization, alternative debugging utilities, and debugging best practices.

    Great If You Want to Go Deep

    I read through the whole book, but still keep going back to commenting out lines of code, creating variables and having them print, using "<>;" to halt printout until I hit enter, etc.

    Still, I'll bet this book is excellent if you do more advanced programming than I do. If you ask yourself, "How do I even test that?" get this book!
