Reseting Bash Prompt Text(Not the color) on RPi

Question

I changed my bash prompt text to just the "π" sign. I really want to change it back to the default but I don't want to reset the WHOLE Pi. I've been looking around on this site and I can't find anything. The linux command I got from http://www.cyberciti.biz/tips/howto-linux-unix-bash-shell-setup-prompt.html doesn't work either. Is there a way to edit /.bash_profile so I can get the default back. Thanks.(I'm running raspbian by the way) I tried to run:

pi $ sudo grep -d skip "PS1" /home/pi

But it just returned:

pi $ 

Answer 1

If you just want to get back the default, you can copy the default configuration files from /etc/skel.

% ls -a /etc/skel
.  ..  .bash_logout  .bashrc  .profile

Answer 2

You can just change the prompt by setting variable PS1.

export PS1="pi $ "

for example, for the shell you're in. But more generally, just change whatever edit you made to set the prompt to π in the first place?
