Usage: put [object|all] [from [container]] into [container]
The put command allows you to put an item from your inventory into a container. You can also use it to move items from one container to another (using with such syntax it's equivalent to use "get from [container] into [container]"). The item to move must be in your inventory. Also, using the keyword [all] in spite of an object will make you put all items in your hands inside the target container.
The target container is first being looked for on your person, and if not found, on the ground.
