Top Forums UNIX for Dummies Questions & Answers Help with solution to add together columns of large file Post 302850005 by torchij on Tuesday 3rd of September 2013 05:49:59 PM

I know awk would be best for this, I haven't been able to figure it out. I'm quite the newb. It's the "every 2 columns" part that I don't know how to code.

I know how to do this:
Code:
awk -F "\t" '{print ($2/($3 + $2 + 100))}'

But I'm not sure how to do columns 2&3, 4&5, 6&7, 8&9

Many thanks for the help.
