Re: multiple profiles

Thanks, for the reply!

So I have to check manually? no way nmcli saying file exits and quit. (because it will still make a file with name ifcfg-xxx-1 if ifcfg-xxx exist).

The NetworkManager client tool (like nmcli, or a GUI) in general does
not know which file name will be chosen. In the NetworkManager API you
can see the file name (like 

 - `nmcli -f all connection` 
 - `nmcli connection up filename "$FILENAME"` 
 - `nmcli connection load "$FILENAME"`

but the client tool cannot pre-determine which file name will be used
when adding a profile.

If you care about the filename, create the file instead of using `nmcli
connection add` (followed by `nmcli connection reload`)

But is your problem really the filename here? It seems, when you add a
new profile, it would be good to choose a name for it, and don't let
nmcli automatically choose "ethernet" and "ethernet-1". Just do:

  nmcli connection add type ethernet con-name xxx

"con-name" is an alias for "", and contrary to what one
might reasonably expect, the "id" is not enforced to be unique:

$ nmcli connection add type ethernet con-name xxx
Connection 'xxx' (7f23f5cd-90f3-4cd8-8612-cf5d0856b130) successfully added.
$ nmcli connection add type ethernet con-name xxx
Warning: There is another connection with the name 'xxx'. Reference the connection by its uuid '8811722f-d662-48c5-9271-c8aa764d8f4a'
Connection 'xxx' (8811722f-d662-48c5-9271-c8aa764d8f4a) successfully added.

It's a good idea to ensure yourself that the is unique.
That means, before you add a new profile, check the existing names in
`nmcli connection` output and choose a different name.
