NAME¶nm-online - ask NetworkManager whether the network is connected
DESCRIPTION¶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 below).
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.
OPTIONS¶-t | --timeout seconds
-x | --exit
-q | --quiet
-s | --wait-for-startup
EXIT STATUS¶nm-online exits with status 0 if it succeeds, a value greater than 0 is returned if an error occurs.
