I want to run a server on my mac, but i keep getting this message when i type "cd /Users/Jordan/minecraft/minecraft-server" (without quotations)

"-bash: cd: /Users/Jordan/minecraft/minecraft-server: No such file or directory"

I have followed this (http://www.worldofminecraft.com/node/3955) exactly but i cant get it to look like this (http://imgur.com/xnFcj.jpg)

Any help would be greatly appreciated.
