If my assumptions and calculations are right, then that number is way above 10240.

Anyways, why a for loop when awk alone can do it ? I think this should work as well.

Code:

awk -F'-' '{print $3"/"$1"/"$2}' /home/priyank/try_2/data3/date.txt >> /home/priyank/try_2/data3/cool.txt

I hope this is no homework question.
