Sounds like your PATH environment variable got reset or messed up in some way. Can you echo your path to see what it's set to (just wrapping it in pipes so that if PATH is empty you can still see that the echo succeeded):

$ echo "|$PATH|"

If that result is empty or lacks something like /bin or /usr/bin, then that is probably your problem. You'll need to track down where that is getting messed up and fix that. You should be able to still run commands, you'll just need to do so using their full path, something along the lines of:

$ /usr/bin/vim ~/.bash_profile

That path may differ on OSX.
