Google treasure hunt (Second puzzle)

Its about time (936266827 seconds before Y2K38) i.e 19may2008 17:07:58 (UTC) and the second puzzle is live (Check it out). You can still try the first question here. Second puzzle from google treasure hunt is to calculate

Sum of line n for all files with path or name containing pattern and ending in particular extension. Similarly Sum of line m for all files with some pattern.
Hint: If the requested line does not exist, do not increment the sum.
Multiply all the above sums together and enter the product below.

for a given set of files contained in a zip archive. I have already submitted my answer , but this time I will have to wait for 24hrs to check the status of my answer . I thinks its a good puzzle to test your quick shell script abilities. (Can also be done easily in perl/python).

For the solution part, I wont give the actual solution (As dont want it to spoil for others who are actually trying) but you can use shell commands [grep, find ,sed and pipe (|)] to get to solution. You can get all the required numbers in 2 lines on shell.

Sweet! I beat you My submit time was 2008-05-19 17:46:47.788098. I was concerned because I was surfing while waiting for the start time and became distracted - which caused me to start 3 min late.

I did mine in Java as forgot about shell scripts. That might have been faster to write.

Cheers.

Actualy friends I stay in India and I get access to internet at 10.30 in the morning. So I replied at 2008-05-20 05:27:55.247648 UTC

However friends, I did not find any twist or difficulty in this question. Like in teh previous puzzle the answer could not contain in a 64 bit variable.

I know, this might be regarded lazy, but I found it easier to use search on this one. Formed a boolean query with some wildcards… ultimately gave me the same solution as my script

And my answer is correct . Though this was not that difficult of a question.
