Unfortunately, Mac OS X's version of ping doesn't seem support the flag - it doesn't work if you try to use it, and it's not listed in the man page. Some versions of the ping command support the -b broadcast flag, which will send a ping request to any device capable of receiving such requests on your network, and report back with the addresses of those that replied.
So I wanted a simple way to just poll my network and see what was out there, which would let me find the camera by process of elimination. I plugged it in this weekend, but couldn't even begin to remember what IP address I'd assigned to it. We've got a wireless video camera, but I've had it unplugged for a very long time. Over the weekend, I "lost track" of a device on my network. Experienced Unix users, look away now, please - the following is a very simple hint.
