This is my first post, so I'm not sure if I'm in the right section or not. I have downloaded Xcode and it runs just fine. But now my terminal commands always return the message "commands not found" I've attempted a little trouble shooting and I've gotten no where. here is what happens when I do echo $PATH /usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin Any help would be appreciated. Thank you.
