Home folder name changed but terminal prompt is still showing last name I changed the name of my home folder in 2 ways. First I change it using the instructions from the official Apple website: 

sudo mv /Users/old_name /Users/new_name

and then I also changed it going to System Preferences > Users &amp; Groups > Advanced Options. 

My problem is that the prompt on the terminal is still showing me the last name I had

name-mbp:~ old-home-folder-name$


why? 

Is it possible to make changes have effect also on the terminal?
What the terminal prompt is showing you is not the home folder name, but the user name.

The folder is displayed after the machine name, in the ~ highlighted below:

name-mbp:~ old-home-folder-name$
Folder   ^ ^ User name


You can type the command pwd ("print working directory") to see which folder it is currently in. Or you can type the command echo $HOME to show you what Terminal thinks your home directory is.
