Need help with this tutorial

[Jwag598]

Hi, I'm following a tutorial for BT4 that uses mdk3, and uses this command: "cd /pentest/wireless/mdk3" I'm using BT5 and and when I use that command I get this: "bash: cd: /pentest/wireless/mdk3: No such file or directory" I messed around for a bit trying to figure it out (I'm a newbie), but I need help. So you get my predicament, and could someone help me so I can continue with the tutorials?

Thanks in advance
