actually create fd is unnecessary but maybe it can be like below that you want Smilie
Code:
#!/bin/ksh
>extract1 ;exec 3<file1 ;i=200
while :;do
if [[ $i -ne 0 ]] ; then
 read -r line <&3 ; echo $linecount $line>>extract1 ; ((i--))
else
 for (( i=1 ; i<=500 ; i++ )) ; do
  read -r line < file2 ; echo $linecount $line>>extract1
  [[ $i -eq 50 ]] && exec 3<&- && more extract1 && exit 0; done
fi
done
