which which [object-type] thing-to-match. This command shows you what things match you query. For example, if you have a player named "Igor The Ferret" and an object called "ferret chow", a "which ferret" will show you both matches and their object ids. A "which object ferret" will only show the "ferret chow", however. Since the look command does not show object ids after the names of things you own, the 'which' command is the quickest way to find out the number of any particular object.
