A practical look at why we're moving from traditional network script files to NetworkManager CLI on RHEL systems. We'll walk through the basics of nmcli, showing you how to view connections, manage network interfaces, and work with configuration parameters - all with real examples on a live system. This isn't just theory - you'll see exactly how to disable interfaces, handle DHCP configurations, and understand why this modern approach makes automation easier than old-school file editing. Perfect for anyone making the switch from legacy networking tools or just wanting to get comfortable with nmcli's command structure.
