I want to get a list of Ethernet and wireless connections from the terminal. Those connections are listed in NetworkManager's GUI and include info like the connection's SSID.

The next step is to delete unwanted connections.

    All NetworkManager connections are located in: /etc/NetworkManager/system-connections/

    So you can easily use ls to get a list of them:

    ls /etc/NetworkManager/system-connections/

    then remove the one you want:

    sudo rm /etc/NetworkManager/system-connections/some-connection

    You can also use nmcli tool, which is a better idea:

    To get a list of connections:

    nmcli connection

    To get informations about a connection:

    nmcli connection show connection-name

    You can pip it to grep to look for specific info:

    nmcli connection show connection-name | grep ipv4.dns

    To modify a connection:

    nmcli connection modify connection-name config-name new-alue

    Example:

    nmcli connection modify HomeNetwork ipv4.dns 8.8.8.8

    To delete a connection

    nmcli connection delete connection-name
