I want to learn how to script but i dont know where to start can someone share a ling or something on where i could start.
The way that I learned Lua was basically by studying other players scripts, and pretty much by learning from my own mistakes. There are plenty of resources to help though, if that isn't an option for you. Here are few resources you can check out:

I hope this helps you out. These are just a few of the many resources that you can use to get started with lua. Remember, you obviously won't be an expert right away, but don't give up. You'll get the hang of it :P
