Add Sudo

Adding sudo and adding users to sudo

sudo is often a vital tool when working with Linux based systems as it allows you to elevate your privileges to run commands as an administrator when required.

Installing sudo

On some distros like Debian 10 (Buster) sudo may not be installed. This means scripts leveraging sudo from regular users will fail and users must switch user to root before running elevated privilege commands

To install sudo:

1. Switch to root user

    su -
   

2. Install sudo using your appropriate package manager

    apt install sudo # Debian/Ubuntu
       
    yum install sudo # RHEL7 and earlier
       
    dnf install sudo # Fedora and RHEL8
   

Adding user to sudo group

1. While still logged in as root run

    usermod -aG <username>
   

2. Exit root
3. Logout and back in as user
