Members of the sudo group can execute any command as root user using the sudo command:
sudo date
The command above invokes the date command with root privileges.
In order to add a user to the sudo group, invoke the following from a terminal:
sudo usermod -aG sudo <username>
The leading sudo runs the usermod command as root. Depending on how a user is configured, the sudo command may prompt the user to enter a password.
To add a user named, devops, to the sudo group invoke the following command:
sudo usermod -aG sudo devops
