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 <timeout_value> Time to wait for a connection, in seconds. If the option is not provided, the default timeout is 30 seconds. -x, --exit Exit immediately if NetworkManager is not running or connecting. -q, --quiet Don't print anything.
0 Success - already online or connection established within given timeout 1 Offline or not online within given timeout 2 Unspecified error
