Top Forums Shell Programming and Scripting Awk: Assigning a variable to be the value of FNR at a certain line Post 302961882 by ThomasP on Saturday 5th of December 2015 04:22:09 PM

That's the thing I did something similar and it didn't give me the correct FNR instead it seemed to reevaluate the variable (max_line in your example) to =NFR

Although I'm not sure whether I put that printf() in the END section, then it the variable might not get reevaluated
