Are you sure you really want to do this?

Usage: murder <victim>

Murder allows you to attack and attempt to kill another player.

If you try to kill a player in an area that is not a PK-area, you will get a
KILLER flag, which allows anyone to kill you for any reason. If you are flagged
as a killer, other players will be allowed to use the MURDER command to fight
you without being flagged themselves.
