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
-tkc
