Many thanks Adam, I?ll give this a go. Btw I think you?re correct
regarding dash. Also agree a return code would be useful if available for
debugging...

If you are able to reproduce it, run motion with -d 9 to get verbose
log and try to analyze it (or share here)
It should give you more info when and which script got executed
