solution 1)  search the list archives...within the last week, 
someone wanted to count unique lines in an input file.  Several 
solutions were given--one of which solved it by counting 
instances of each unique line using a set.  The resulting 
dictionary can then be sorted (by key or value) to yield your 
desired results.  Tweak accordingly.

solution 2)  using common *nix shell commands:

	bash$ sort in.txt | uniq -c | sort -nr
