This morning I was in a scenario where just done an install (Fedora 29
Server), and the device had no wired network, only wifi. I was feeling
lazy and didn't want to pull out my USB ethernet dongle and a cable. So
out of curiosity, I was wondered how far I could get with the new nmcli
(Network Manager CLI) tools, and tab completion.
The answer, all the way to working wifi networking. So I thought I'd
share the FYI. I see this coming in really handy for Raspberry Pi 3/3+
and Zero-W owners.
Example output:

And that worked!
Best part, it also created all the needed files in
/etc/sysconfig/network-scripts/ for this network, set to start onboot
even! Very handy.
