My personal CentOS configuration scripts: installs elrepo, epel, enables centosplus and PowerTools, sets sudoers to require root password, enables some nano settings, fixes dnf tab completion if system is centos 8. Written on CentOS 8, only somewhat tested on CentOS 7
#!/usr/bin/env bash
if (( EUID != 0 ))
then
echo "Script should be run as root"
exit 1
else
echo "Detected running as root"
fi
