With this command you may bury a rotting corpse. You can bury it normally, or you may choose to bury it a little more creatively. How you bury the dead depends upon your character's moral outlook.
bury corpse good/evil
You can try to bury an item in your inventory in the ground where you are (if you are outside) or perhaps in some kind of planter, pot, or other such thing if you are indoors.
bury <item> with <tool>
bury <item> with hands
You might want to retrieve this item at a later time, so see also dig.
