Book description

Wicked Cool Ruby Scripts is a compendium of scripts that will make your life easier by saving you time and solving problems. If you find yourself wasting effort and time on a task a trained monkey could do, it's time for Ruby to come to the rescue.

Wicked Cool Ruby Scripts provides carefully selected Ruby scripts that are immediately useful. Learn how to streamline administrative tasks like renaming files, disabling processes, and changing permissions. After you get your feet wet creating basic scripts, author Steve Pugh will show you how to create powerful Web crawlers, security scripts, full-fledged libraries and applications, and much more. With each script you'll get the raw code followed by an explanation of how it really works, as well as instructions for how to run the script and suggestions for customizing it. Wicked Cool Ruby Scripts will save you from the tedium of repetitive tasks and give you back the time it would take to write scripts from scratch.
