Check out HISTIGNORE. It's not about duplicates, but I use it to get rid of 
things I do constantly but which I don't really want in the history, like: 
cd, td, fd, wd, ll, ls, lf, lt, j, ok (yeah, most of those are aliases or 
shell procedures I define as shorthands for or embellishments of common or 
built-in commands: td (pushd), fd (popd), wd (pwd), ok (echo ok^G), j (jobs)).

HISTIGNORE repsects glob wildcards, by the way.

You might get better results from this than from duplicate control. At 
least it can be complementary.
