For further reference, the simple solution is always the best one.
I now have the following:
COUNT=0
for URL in `grep "^https" ${INFILE}`; do
process ${URL}
if [ $? -eq 0 ]; then
COUNT=`expr ${COUNT} + 1`
fi
done
echo "URLs processed: ${COUNT}"
There now is no piping step (and therefore no subshell) involved.
This works and can be easily extended (more preprocessing from
the input list file).
I have no idea why I didn't think of this in the first place... :-)
