awk - find first instance of string after NR==10
How do I use awk to find the NR of first instance of a specific string after eg NR==10?

I need to find the first instance of the word "class" after a specific NR.

To bail out after the first occurrence of "class", modify vgersh99's {print FNR} to {print FNR; exit}.
