How to Change the Username for a User on Ubuntu

How do you change the username for a user on the Ubuntu operating system?

You can do this by using the usermod command native to Ubuntu, which modifies the system account files depending on the options you give it.

The command for updating a user's username would look like this:

    
      sudo usermod -l new_username current_username
    
  

The name of the current user (current_username) will be changed to new_username.

When you run this command, nothing else is changed on your machine. Therefore, you should manually rename the user's /home directory to reflect the new username.

You can read more about the usermod command in the Ubuntu manual.
