I am trying to change my current username on Linux Mint that shows up when I open a terminal window.
Currently:
john@myLinux
I want to change to:
gary@myLinux
I have tried:
(1) Start -> Settings -> Account Detail and altered the 'name' field.
(2) The steps mentioned here: https://askubuntu.com/questions/34074/how-do-i-change-my-username
(3) Altering the passwd file: https://www.cyberciti.biz/faq/understanding-etcpasswd-file-format/
Option #3 seems to affect the username displaying in the terminal window but causes issues with logging in(my password becomes incorrect).
How can I successfully change the username that is displayed in my terminal window on Linux Mint OS?
