How do you get rock smash on pokemon pearl?
Go to Jubilife. When you get to the entrance go straight. Keep going. When you get to the pokemarket, (like a pokecenter but with a blue top) you go straight then turn right. Keep going til you reach the cave (opening on the side of the wall). Right when you walk in, you will see a guy talk to him. You have to beet the Gym Leader to use the item.

You'll need to defeat the relevant gym leader & then once you have the TM for the move, teach it to one of your pokemon. Have you gotten any gym badges yet? I think you need to beat either one or two gym leaders to get it (it's either the first or second one that you get the TM from).
