If you are connected to a VPN, this command will return a list of established
VPN connections:
nmcli con status | grep -oP '^(([^\s]+\s){1,}[\s]{2,}){4}yes.+$'
This command will list the IDs of any established vpn connections (one per
line):
nmcli con status | grep -oP '^(([^\s]+\s){1,}[\s]{2,}){4}yes.+$' | grep -oP
'^.*?(?=\s{2,})'
So to disconnect all VPN connections you could do it based on this ID like this:
nmcli con status | grep -oP '^(([^\s]+\s){1,}[\s]{2,}){4}yes.+$' | grep -oP
'^.*?(?=\s{2,})' | sed 's/^/\x27/' | sed 's/$/\x27/' | xargs -L1 nmcli con down
id
However, perhaps it is better to do this using the UUIDs.
You can list the UUIDs of all established VPN connections like this:
nmcli con status | grep -oP '^(([^\s]+\s){1,}[\s]{2,}){4}yes.+$' | grep -oP
'(?<=[\s]{2})[^\s]+(?=(\s+[^\s]+){2}\s+yes.*)'
So you can disconnect all established VPN connections by UUID like this:
nmcli con status | grep -oP '^(([^\s]+\s){1,}[\s]{2,}){4}yes.+$' | grep -oP
'(?<=[\s]{2})[^\s]+(?=(\s+[^\s]+){2}\s+yes.*)' | xargs -L1 nmcli con down uuid
Perhaps this logic could be added to nmcli, so that this following proposed
option would concisely achieve the same results:
nmcli con down allvpn
