Track

From Wormhole Sci-Fi MUD Homepage

Used for finding the first step on the shortest route to a monster. Until you find the monster, each time you enter a new room the next direction will be given to you. Some MUD clients can react to this information, enabling a form of 'autotrack'.

Note that it is not always possible to find a direct route to someone! If you have to use a transporter to get there, track won't help. Also, be warned that tracking can lead you into an ambush, or (theoretically) a deathtrap.
