The Secure Shell program supports a number of command line flags to control behavior on a per-connection basis. These are not to be confused with the various terminal preferences (like colors or fonts).
--config=<name>This is a shortcut for setting other options so people don't have to remember the full list. At the moment, the only config supported is google.
--proxy-host=<host>The host to use as a relay server. All connections will be made via this server.
--proxy-port=<port>The port to connect to on the relay server.
--use-ssl=<bool>Whether to use HTTPS (the default) or HTTP.
--ssh-agent=<extension id>The extension to use as an ssh agent. All auth requests will be forwarded from the ssh session to this extension for processing. It can be used to manage keys or certificates or anything else an ssh agent can.
