How do I tell tor, from the command-line, to give me a new identity in a Mac?

Is there a way to ask tor/vidalia for a new identity, via the command-line, as opposed to mousing to the icon, bringing up the menu, and clicking the option there?

I'm running Mac OSX 10.6 and 10.7 with the stable install 0.2.2.32-0.2.14.

Open a telnet connection to the control port of your Tor service and send it SIGNAL NEWNYM.
