There is a difference between the two approaches.     Writing through
a pipe to "head -8" will kill the writer when the 9th result is
printed.   If the cost of finding an additional match is significant
(or only N matches exist) then there is a potential waste of resources
involved in finding the extra match.   For most uses this is not a big
deal and the approach using "head" works just fine.
