nmcli

nmcli is a command-line tool used for managing and configuring network-related settings in Linux-based operating systems, primarily NetworkManager. It allows users to interact with NetworkManager without needing a graphical user interface.

With nmcli, users can view information about network connections, including Ethernet, Wi-Fi, and mobile broadband devices. It provides details such as device status, IP addresses, DNS settings, and network speeds.

Users can also edit and configure network settings through nmcli. This includes creating or modifying network connections, enabling or disabling devices, setting up Wi-Fi hotspots, assigning IP addresses, configuring DNS servers, and managing connection priorities.

nmcli supports various network protocols like IPv4 and IPv6, and it also supports NetworkManager plugins for specific networking technologies such as VLANs, bridging, and bonding.

Furthermore, nmcli supports scripting and automation by providing options to execute nmcli commands directly or by referring to configuration files. This allows for easy integration with shell scripts or other automation tools.

nmcli is a versatile tool for network management, making it a preferred choice for system administrators, network engineers, and power users who primarily work on Linux command-line environments without a GUI.
