add file name to output file along with the line extracted

[Kishore Reddy]

Dear group,

I am trying to extract 10th line from group of files.

I am able to do it with 

find . -name "*.final.out" | parallel "awk 'NR ==10' {} >> result.txt"

However, I need to add a filename in the output file for every line so that I can identify from which file the line came from.

Any help is appreciated.

warm regards,
Kishore R. Anekalla
