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. |
|
