After you have installed your Ubuntu server, you may want to do some initial setup.
Specifically, you may want to add a another account.
Adding user account
Adding users can be done using the command adduser. In the below command-line, I am creating a developer account call ‘developer’.
$ sudo adduser developer
After you have create the user account, it might be useful to add the account to the ‘sudo’ group so that the account can make use of the ‘sudo’ command. To do so,
$ sudo addgroup developer sudo
You can check which groups an account belongs to using the ‘groups’ command:
$ groups developer
