With Ruby, you can read and write to config files and logs, automate tasks like mail merge, and find and organize files without ever leaving your code editor.

Learn to find existing files and directories and to create new ones. Discover different techniques for reading and writing data to files. Then learn how to import and export data in popular formats and how to use Embedded Ruby (ERB) to bind dynamic values into reusable file templates.
