OpenVPN ctl can be started with command line args to make few operations from the console.
openvpnctl start [--proxy=url] [--remote=n|url] network-name
openvpnctl stop network-name
openvpnctl stats network-name
openvpnctl log network-name
start command
start command waits until initialization is completed. It prompts user for password and so on if required.
If you use --management-signal option you are out of luck with CLI. Upon successfull initalization it disconnects (and kills VPN connection).
Options --proxy and --remote requires correspoinding options --management-query-proxy and --management-query-remote
