Join Bill Weinman for an in-depth discussion in this video Exercise files, part of Perl 5 Essential Training.
- [Voiceover] The exercise files for this course are included with your basic lynda.com membership. If your're a lynda.com member then you have access to the exercise files used for this title. Copy the exercise files to a location where you can find them on your system. I've copied them to the desktop on this system. The exercise files for this course are laid out by chapter. Where each chapter has a folder, and the files for that chapter are contained within the associated folder. Most of the exercise files are simple Perl scripts.
To use one of the files, first make a working copy. So I'm going to select this file and press command c to copy it, and command v to paste it. And then rename the copy. I like to call it 'hello-working'. So I'll just put a '-working' after whatever the name is of the file. And then open it in your editor or development environment. I'm using Komodo Edit. And let's see this is in chapter 2. And so there's my hello-working.
I'll double click on that. That opens it in the editor. And I press shift command r to run it and you see it says hello world down there in my results. When you're done with the working copy you close it in the editor and then you may safely delete it from your exercise files, or you can keep it if you want to work on it more later. The exercise files are here to make your learning experience easier and more powerful. Take your time, experiment a lot, and happy learning.
Watch to learn the details of the Perl syntax, from variables, conditionals, loops, and data structures to regular expressions, functions, and references. A quick-start guide is included for experienced developers who want to get up and running with Perl 5 fast, and the entire course is recommended for both new and experienced programmers alike. Later chapters cover file handling and reusing code with Perl modules, plus Perl best coding practices.
