Сохраняем скрипт в текстовый файл, скажем, под именем nmcli
далее из папки, куда сохранили, делаем:
Код:

sudo cp nmcli /usr/local/bin/
sudo chmod ugo+x /usr/local/bin/nmcli


После чего собственно управление будет таким:
Код:

nmcli connection_name start|stop


То есть чтобы, например, активировать соединение c именем "MyNetwork" пишем:
Код:

nmcli MyNetwork start

Чтобы деактивировать - соответственно stop
Чтобы посмотреть список доступных соединений - просто вызываем скрипт без параметров.

2. Чтобы автоматом запускать vpn после логина в систему:
открываем gnome-session-properties и добавляем туда команду:
Код:
nmcli имя_vpn_профиля start

Лучше если профиль соединения будет системным (см. выше: примечание к части 2)
