Kris, Thanks again
I got that right after more digging in man ksh and baby trying for a long
night.
My code worked well after putting like you said, which I did not understand
initially, but now it is clear.
the code turned out something like
{ while cat /tmp/availspace.$$; do false; done } |&
exec 5<&p
cat /tmp/reprocesses.$$|awk '/DATAFILE/ { print $0 }'|tr -d ' '|
while read file_b
do
read -u5 file_a
echo $file_b $file_a
done >/tmp/reprocessrecset.$$
exec 5<&-
this what you meant ?
Thanks
Dak
