This makes sense With the repeated "Toronto @" jazz.
What about the brackets in the above example ? Should I add a set ?
And what about "< weather.sc | sort" ? With it now parked outside the
do/done set nothing happens. Obvious again, isn't it ? sigh..
I'll try stuff, but right now it doesn't work, and it's shaped like
this;
weather.pl > weather.sc
while read a eq b; do
case $a in
celsius|conditions|humidity|pressure|wind) echo "$a = $b" ;;
place) place=$b ;;
updated) updated=$b ;;
esac
done < weather.sc | sort
echo "$place @ ${updated% on *}"

Alright smart-e-pantz, I /did/ run the code.
It should have been obvious, and is in retrospect, but I have little
experience crafting for/ next loops. From today, when I see unwanted out
repeated so, I will know to look in the loop for the offending error.
I appreciate your methods, both in programming and in forcing me to
consider the workings of the elements. Yeah, I'm learning. I haven't got
it working right, but I'm learning. ;-) I fear I'll never actually be
good at this, but I's fun taking baby steps.
