#Permanent alias

In terminal run the following (pick your poison, editors are separated by the 'or' operator):

nano ~/.bash_profile || subl ~/.bash_profile || atom ~/.bash_profile

Add the following line to your .bash_profile but change goto_sites and the path to your own:

alias goto_sites='cd ~/../../Volumes/Graphic\ Design/sites/'

Restart your terminal

Hey, here you go --> $.
