"home"-string(?) in terminal changed

Question

So, in my Mac OS terminal, the intro letters changed from I can't even remember what they were before to JohannasiPhone.

I don't know what happened or what I did, but it surely wasn't intentional and I would like to reset it to the state it had before. Any suggestions?

Also, I lack the terminology of describing precisely the name of the string that changed there, so I can't add the proper tags I think. If you have suggestion how I can state the problem in more appropriate terms, please leave a comment.

Answer 1

That's the hostname isn't it?

Check out setting of PS1 in ~/.bash_profile or ~/.bashrc.
