I installed the most recent update to OS X Lion (10.7). After I did that, my terminal won't recognize normal commands. I typed
ls and got:
-bash: ls: command not found
I figured I'd try to add usr/bin to my path, but I can't find .bash_profile to edit it since typing
edit .bash_profile won't work. I can't set the Finder to show all files since my terminal won't recognize the commands necessary to do that.
what do I need to do?
