Hi,


UUIDS is a variable containing all the "connection.uuid"s for your Wi-
Fi profiles.

Then, the first "for" iterates over them, and for each connection
profile it prints 5 fields (so you see what is configured in these
profiles).

The second, itereates over the same profiles, but clears the
connection.interface-name and wifi.mac-address properties. These two
properties (among others) tie a connection profile to a certain device,
by clearing them, the profile is applicable for any device, regardless
of the interface name and MAC address. See `man nm-settings` for the
properties. And see `man nmcli` or just `nmcli help` for info about
nmcli.


Does this help?

best,
Thomas
