Have one more query about above solution..

We needed to print ,say "123" a line before occurrence of .sub. How is your code doing the same? Which part of the awk line means "print before .sub".
I need to understand the logic behind it.

Also, how will it change. if say i have to print the same "123" after the ".sub"
I need to understand the logic behind it.

Thanks
