This is the correct answer for Unix-like systems. I don't think hashbangs work out-of-the-box on Windows, and to be honest I don't really know how to emulate them offhand.

I updated my answer for default open method in windows.
#!/usr/bin/env ruby\n p 'hi!'then runchmod 2775 ./file.txtthen you can run./file.txtand the output will be"hi!"
