I ran the chsh command as root to change the shell and editor for root. i then made a stupid mistake and replace my shell with the editor i wanted and the editor with the shell so now whenever i login as root it starts emacs. i realize that this is a stupid mistake. now i need to know where the file with the shell and editor information is. because i should be able to simply edit the file with the root power emacs i have open but i have no idea where it is. thanks in advance for helping me with my stupid blunder
