nm-online − ask NetworkManager whether the network is connected
nm-online [ OPTIONS ]
nm-online is a utility to find out whether we are online. It is done by asking NetworkManager about its status. When run, nm−online waits until NetworkManager reports an active connection, or specified timeout expires. On exit, the returned status code should be checked (see the return codes bellow).
−t, −−timeout
Time to wait for a connection, in seconds. If not specified, the default is 30 seconds.
−x, −−exit
Exit immediately if NetworkManager is not running or connecting.
−q, −−quiet
Don’t print anything.
