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.
