Hello,

There is an excellent article on how to do this here:
https://www.digitalocean.com/community/tutorials/how-to-add-delete-and-grant-sudo-privileges-to-users-on-a-debian-vps

Basically you need to login as the root user (or with root permissions) and add the user to the sudo user list:

sudo visudo

Normally it is better to use groups of which the allowed users are members of rather than add every user to the sudoers file.

But otherwise it is the same, just edit that file.

There are several ways to do this and they change based on the distro you are using.
What distro are you working on?

ok, what you need to do is edit teh file /etc/sudoers
Then, assuming you named you user user1, add the follwing line:

user1           ALL=(ALL)       ALL

Open in new window


You can add it under the line that reads

root           ALL=(ALL)       ALL

Open in new window


Hope that helps

mac_g, manually changing the gid for a user is not recommended under any circumstances, please follow my instruction to provide su access to a user.

after you edited the sudoers file,
the backup user should run the command with sudo before it, or use su to move up to root level before executing the command.
