Hi,

Yes agree 100% with your evaluation. I'm thinking s arching for the file in a directory might be quicker than checking millions of lines of csv. The logic would be:

1. Read the first line of the csv
2. Search the data directory for any file that matches the pattern (not exact, a contains)
3. If path is found, write out to a csv.
4. Move to next line in csv

I'm wondering if this is better done in python or something similar, but would rather stick to grep/awk if I can.

Does that make sense?

Thanks!

Tirm
