Top Forums UNIX for Dummies Questions & Answers get max value every 4 rows between 2 column Post 302673437 by alister on Wednesday 18th of July 2012 12:54:21 AM

Your sample data looks to me to have 4 columns, not 2 (in the future, please use code tags around data to preserve formatting).

Untested:
Code:
awk '$4 > max { max = $4; s = $0 } NR % 4 == 0 { max = 0; print s }' data.txt

If that code helps in finding a cure to some dreadful disease, I expect free treatment if I ever contract it. Smilie
