Making use of sudoers – configuring sudo access

Whenever the system administrator wants to provide trusted users administrative access to the system without sharing the password of the root user, they can do so using the sudo mechanism.

Once the user is given access using the sudo mechanism, they can execute any administrative command by preceding it with sudo. Then, the user will be asked to enter their own password. After this, the administrative command will be executed in the same way as run by the root user.
