Florian, this was a very helpful comment. Thank you. For the benefit of lurkers, I copy some text from http://en.wikipedia.org/wiki/Expect "*Expect*, an extension to the Tcl <http://en.wikipedia.org/wiki/Tcl> scripting language written by Don Libes <http://en.wikipedia.org/wiki/Don_Libes>, is a program to automate interactions with programs that expose a text terminal<http://en.wikipedia.org/wiki/Text_terminal> interface." In my experience, Argyll already integrates well with shell scripts, and I think that at some point Graeme will realize that single measurement is a natural function of a measuring interface, and add a calibration and a no-calibration single-shot measure option.
