Introduction

Summary

By the conclusion of this introductory chapter, you should have a good overview of the Perl debugger itself, and of how this book will approach the subject of debugging Perl programs. You should be able to start the debugger, execute some Perl code or a debugger command, and quit the debugger and return to your operating system environment.

The next chapter will discuss the most commonly used commands for inspecting the environment of your program, and how to list the code and inspect the runtime variables within it. We also find out how to use the built-in help facility to get more information for a particular command from both the debugger and the system itself.
