Thanks Craig :-)

Yes, it's difficult to describe, and that's prolly why I've struggled
to Google it. If one completed a bash script with 'exit 0' and all ran
well, nothing (or null) is sent to stdout. If a script passes a
variable on to another executable, this is may not necessarily be sent
to stdout, but there is something one can pass at cli time that does
copy this/these var(s) to stdout to see what same script produces.

I hope this makes sense :-)
