The number of records which is NR contains the current line number. awk has an END{} block, where when it is reached NR will have the number 21 as value in your case.
Anyway, I second what the others say, that the least complex tool needed to do the job might be the tool of choice.
If I got it right, you just want to read an input file and do something with every line.
This could generally also be done with something like this:
Code:
while read LINE; do
echo $LINE
done < infile
...where the echo could be something else of course.
This way you don't even need to know how many lines you have to use it in a for-loop, as it cycles over every line anyway.
