Recently, I changed my terminal prompt name to get rid of everything except the dollar sign. I did this a while ago, and from what I remember, I used System Preferences to make the change rather than my terminal. I want to change my name back to the default settings now, but I'm not sure how to undo this through System Preferences.
echo $0 gave me an output of
cat ~/.zprofile | grep -i ps1 output nothing and just printed
$ on a new line.
