[2] Actually I am not happy with this but couldn't think of a way to do
it better. Having to fork the subshell costs about 60 seconds of system
time and 10 of wall time.
Here's one way to do it. This is quick and dirty and I haven't
benchmarked it, but I imagine it would be faster.
while read one two discard; do
case "$one" in
WWW:) echo one: $one two: $two
case "$two" in
http://*) echo WWW= $two ;;
*) echo WWW= http://$two ;;
esac
break
;;
esac
done < pkg-descr
I did test this briefly and it pulls out the right values for
variables with and without http://.
