How to add user in Ubuntu and assign root rights ?
Let’s start learning how to add user in Ubuntu and assign root rights to it. When you install any OS on your server, you will be assigned root access to that server. Root will have privileges to execute any command which can cause severe issues with your server in the worst case. Sometimes a command that has been executed accidentally can disrupt the working of the server. To avoid this, first of all, add a user account to limit access of commands. If you want to allow the user to execute administrator commands, you must add it to ‘sudo’ group. You can execute any command with root rights by using ‘sudo’ keyword at the start of that command e.g. sudo apt-get update
adduser above_username sudo
The first command will add a new user to users’ group, the second command will add the created user to ‘sudo’ users’ group.
