[gentoo-user] Help with bash/awk script

[Ow Mun Heng]

I'm trying to figure out how to do this sequence in this bash script.
The problem I'm having is how to make $i to change according to the
changes in $x

My current solution is a bit of a hack and stupid.

One more thing, my current solution will parse the file _each_ time for
_each_value/head which essentially means it reads the file multiple
times. Is there a better way so to reduce the # of reads/parses? (Does
awk parse the file once or multiple times, that is if I were to rewrite
the below entirely in awk language)

Thanks
