So I move between multiple networks in the same facility all day. About 20 or so. In Windows, I wrote scripts using the netsh command to allow me to simply exectueta batch file to switch me over to a pre-defined static IP Address on each network. Can someone point me in the right direction in doing this on OS X? I would like to do it thru the GUI if possible, but will consider a shell script if there is no toher alternative. Thanks in advance.
