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
