The command "nmcli networking connectivity check" is used in Linux to check the connectivity status of the networking subsystem.

Specifically, the command uses the "nmcli" tool, which stands for Network Manager Command-Line Interface, to interact with the Network Manager daemon. The "networking" parameter indicates that the command pertains to the networking subsystem.

The "connectivity check" part of the command refers to the action being performed, which is to check if the system has an active and functional network connection. When executed, this command sends a request to a predefined server to determine if the system can establish a connection and receive a response.

The output of the command will indicate the connectivity status, typically as a result of a ping test. If the system can successfully establish a connection and receives a response from the server, it will report that the connectivity is "full". If there are any issues or if the connection fails, it will report that the connectivity is "limited" or "none".

In summary, the "nmcli networking connectivity check" command is used to check the status of the network connection and determine if the system has a functional network connection.
