Just to add on to pfaut's comments, the messages boards are the wrong place to ask such questions, as yopu will not receive a positive response from everybody. I'll tell you right now that we *will* help you with such questions, as you've already been shown. I will make one recommendation: for simple questions (especially related as to how to run a command-line program), first look at the man page or try appending '--help' or '-?' to the program name to see the help. If you can't figure it out from there, I suggest posting to the chatterbox nodelet instead. Simple questions like these are always answered honestly and promptly, and it will not irritate many people at all.
