help ls

ls
ls <object>
ls [object] as <pattern>
ls show columns

Displays a list of all objects within the current room, showing (from left to right), the type of object, the zone that the object belongs to (if applicable), the name of the object, the object ID, and if the object is an exit, the direction of the exit and the ID of the room that it points to.

If an object is given, displays details for that object instead of the current room.

<pattern> is a standard multistat formatting code. Not for the faint of heart! The ls command has its own set of columns; list them by typing ‘ls show columns’. The default pattern is St$s{zone}<Zone>ni?xT.
