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 bellow).

options

-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.

exit status

0

Success - already online or connection established within given timeout

1

Offline or not online within given timeout

2

Unspecified error
