My first attempt would be to skip the hash altogether and just run the 'keys' straight through "/usr/bin/sort -u" as they are extracted. But perhaps the hash is needed for other than eliminating duplicates. (Yes, I have "sort -u" on Windows -- it is just one of many useful things that came with cygwin.)
