Read Files on the Fly

Hi,
I am creating files in a folder on the fly with arbritrary names but same extension (say, ".img"). How can I read each filename from the folder through a script.


regards

Is your requirement is below :?

Code:
for fname in`ls /fly/*.img`                                                                                                  do
echo "File name is :$fname"
done

Correct one is :
Code:
for fname in `ls /fly/*.img`                                                                                                    
do
echo "File name is :$fname"
done
