I have now run into a system for which neither of the previous two methods mentioned seem to work. A third method is to use GNU screen. Roughly it is done by:

1. executing “screen”
2. running the command
3. detaching the screen using Ctrl-A, Ctrl-D

However, there is so much more to screen than that. I have had my eye on it for a while, but never made the leap to using it consistently. A couple of handy guides to screen should give some idea of what it can do. I’m going to try out automatically running screen when logging in in an attempt to start using it all the time.
