wikiHow to Execute a Script at Startup on the Raspberry Pi

The Raspberry Pi computer is a great tool for creating all kinds of interesting DIY projects and computer-powered builds. Whether it be used as a media center, web server, gaming console, or simply a computer, there are countless reasons why you might need a particular program or script to automatically startup when the Raspberry Pi desktop loads. While there are as many ways to run scripts at startup as there are uses for the Raspberry Pi, executing a script when the desktop environment boots is the easiest method with the most versatility.
