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).
By default NetworkManager waits for IPv4 dynamic addressing to complete but does not wait for the "auto" IPv6 dynamic addressing. To wait for IPv6 addressing to complete, either (1) change the network connection's IPv6 "may-fail" setting to "no", and/or (2) change the IPv6 addressing method to "manual" or "dhcp", to indicate that IPv6 connectivity is expected.
