@mvattr

command: @mvattr <object>=<old>,<new>[,<copy1>]...

this command moves attributes around on an object. the attribute <old> is renamed <new> (and is copied to <copy1>, <copy2> and so on if specified). if you cannot modify the <old> attribute (for instance if you are trying to move the last attribute, or if it were owned by another player), then a new copy is made and the original is not removed.
