Well, it took a lot of searching and what not, but I finally got to where I can once again execute commands in the Terminal. After much frustration, I was about to give up, but decided to look at the Terminal Inspector window, and it showed that there were three processes running, login, bash, and what. I then opened Activity Monitor, and killed the "what" process, my terminal window executed a couple of commands, and then went to the admin$ prompt. YAY!
Now my question is, how to I stop the "what" command from executing every time I open a new terminal window?
