The nmcli command is a command-line interface for NetworkManager, which is a tool for configuring and managing network settings on Linux systems. The nmcli command consists of different subcommands that correspond to different aspects of network configuration and management. The subcommands are:
nmcli general: shows status and permissions of NetworkManager, as well as system hostname and logging level and domains.
nmcli connection: enables you to create, modify, activate, deactivate, delete, and show network connections.
nmcli device: enables you to show, modify, and control network devices, such as interfaces, bonds, teams, bridges, etc.
nmcli monitor: monitors activity of NetworkManager and watches for changes in the state of connectivity and devices.
nmcli networking: enables or disables overall networking.
nmcli radio: enables or disables radio transmitters for Wi-Fi, Bluetooth, and WWAN devices.
nmcli agent: registers as a secret agent that provides and caches network credentials.
The other options listed are not valid nmcli subcommands. There is no nmcli ethernet, nmcli wifi, or nmcli address subcommand. However, nmcli device and nmcli connection can be used to configure and manage Ethernet and Wi-Fi connections and addresses. Reference:
