Top Forums UNIX for Dummies Questions & Answers awk Grouping and Subgrouping with Counts Post 302776027 by JoshCrosby on Tuesday 5th of March 2013 10:54:53 PM

Thank you so much, based on the dataset it is perfect.. however on the larger files it takes quite a while which is fine. The one issue is that its not taking product (column 1) into account and seems to be grouping on the count

Any ideas? I sincerely appreciate your help.

Some logic
-> product (sort by top 3 - based on how many rows it appears on)
----> skew (sort by top 5 skews from the products found above)
----> count of skews

I hope that helps explain a bit more.
