Here I'll write about small 'uniq' recipe.
I've downloaded CADO-NFS git repo.

You see, there are many French uni domains. Which French uni provided most authors to that project?
Using 'cut', drop everything before the '@' sign to get a list of domains:
% git log | grep Auth | sort | uniq -c | sort -n | cut -d '@' -f 2 ... lix.polytechnique.fr> gmail.com> inria.fr> gmail.com> inria.fr> univ-lille1.fr> inria.fr> lix.polytechnique.fr> ens-rennes.fr> inria.fr> loria.fr> loria.fr> lirmm.fr> inria.fr> lirmm.fr> gmail.com> lix.polytechnique.fr> ...
Collecting statistics of domains:
% git log | grep Auth | sort | uniq -c | sort -n | cut -d '@' -f 2 | sort | uniq -c | sort -n

INRIA provided most -- 13 developers. LORIA -- 7. To get this information, I spent just ~1 minute.
Another usage of 'uniq -c' command in my blog.
