2 cases are offered to you:
Either you are a true newbie therefore your post should be in Q/A for dummies... where you would be helped in understanding what are commands, what they do...
Either you have some command knowledge and are fighting in putting them in good sequence in order to produce the expected result, in which case where is the faulty script?
Have you tried the above suggestion?
What's wrong with it?
