Install and use Sudo in Debian
Most of my experience with Linux is via the Ubuntu distribution, which includes sudo as a default. Debian does not have sudo or superuser accounts, here's how to add it and set it up.
Install sudo:
apt install sudo -y
Once installed, add a user to the sudo group:
usermod -a -G bob sudo
Now logout of root and login to the user that was just added to the sudo group, and verify the user is authorized:
sudo -v
