Ok. So I have my computer sitting next to mine. It's a standard RedHat 9 box with standard installs set. I set up an account for me to log onto with minimal access. I do however have access to a vi editor. So I type in my source code. How do I save/run this code as a command? In other words my question is so simple most books don't have it. How do I save my script and run it? This question I realise isn't very hard, but I cant find the answer.
