When I start the X11.app then it launches an xterm automatically. I've long since switched from the "ordinary" xterm to rxvt-unicode so the initial xterm just hangs around like a wallflower never being used. Whilst it's not particularly bad, it spoils the look of the place so I'd like to stop it launching. How do I do it?
I searched for an answer to this one (here and on the internet) and couldn't find it. I've just found something that seems to work so thought I'd post it here. So so long as this isn't closed - it might be a duplicate - I'll post my answer. Unless someone else knows it and wants to get in first.
