Oliver,
You are making a good point but connecting two different subjects.
The algorithm with awk is still the fastest in theory.
It uses a hash table which runs at O(c) for each comparison
ASSUMING you have a good hash function that yields such result.
The total number of comparison is O(n) or O

It's unclear why there are two "cut" commands. The 7th
field isn't used at all. Also, the -E option to grep
After the first cut the s

Recently I decided it would be time to upgrade an older laptop that
was still running 6.2-RELEASE to a more recent release 7.1-RELEASE (re-
