How hack use?

I open up the game I want to play and then type in lua_openscript_cl (Hack).lua into the console and nothing happens. I have tested this 3 times and still. Is there anything im missing?

I'll be the first to tell you, yes, yes you are, indeed, missing something. That's all I have to say.

I have put it in my garrysmod folder
