Graeme, Something like this? #!/bin/sh ARGYLL_NOT_INTERACTIVE=1 export ARGYLL_NOT_INTERACTIVE theargyllroot/Argyll/bin/spotread -v -e -N IS there a way to make it do a single reading? The script goes off and triggers some external devices, and then comes back and wants to do another reading at a time not precisely known, a few seconds later.
