Supermarkets sell peppercorns with or without little grinders built into the tops of the jars, or white and black pepper already finely ground.
poivre blanc: white pepper
poivre cinq baies (or 5 baies): black, white, green, pink and piment de la Jamaïque peppercorns, usually pre-crushed although you can find it with the little mill on top of the bottle
poivre concassé: crushed peppercorns for grilled meats
poivre en grains: whole peppercorns
poivre moulu: ground pepper
poivre noir: black pepper
poivre rose (also known as baie roses): the ‘false’ pink pepper from Brazil, usually sold as berries, popular on salmon and foie gras
poivre sichuan (or baie de sichuan): Szechuan peppercorns (more and more available these days, even in the supermarkets).
