Thank you for your kind reply, Vladimir. I failed to find the probe
command - I promise - I spent quite a few hours digging through the
source. As for the $((...)) and $[...] - I'll look into it.
It seems that my paltry contributions are not needed, after all.
Bash syntax will not have the min/max behaviour though unless you use a
kind of modulo which will make it complex.
ie. normally you would do that with: x = (x + 1) mod 4, or x = (x - 1 +
4) mod 4.
although I'm not sure a standard "round robin" function like that would
be meaningful but who knows.
so the " arithmetic --set fred --min 2 -- max 10 "1" "+" "2" "
will come down to
fred=$(( (((fred-2) + 1) % 8) + 2 )) -- I assume. Or if you still had
those min/max functions it'd come down to ?
arithmetic --set fred --min 2 --max 10 $(( fred + 1 )) ?
Regards.
