Topic: how to executing system command


I'm really new for rails and I know that this is not the first time about this question, but please, I really need your helps. I've tried to executed the unix command via rails using exec() and system() but didn't work. Could anybody please suggest me how to execute unix command (I'd like to run a shell script) and get it's result to display in the view. Thanks in advance for any help you can offer.
