Thanks for the reply,
Code:
 
 
filefound=0
 
while [[ $filefound -eq 0 ]]
do
 
if [[ -f abc.dat ]]
then
mv abc.dat xyz.dat
filefound=1
fi
 
done

In the above if the file is not found the loop keeps iterating, adding a sleep command will introduce some wait between iterations. Just wondering if by adding the sleep will add any advantage in terms reducing processor load OR it just doesn't make any difference.

Thanks
Zulfi
