I'm not sure quite how your directories are arranged, but you should be
able to take the output of ls for both directories, awk, sort, uniq -c,
egrep, and get a list of files that are duplicated.  For example, suppose
the directories are called dir1 and dir2, then this works on my system
(Solaris 2.6, so check the output at different stages in the pipeline to
be sure it works for you):

ls -1 dir1 dir2 | sort | uniq -c | egrep '^   2' | cut -c 6-

It gives a list of all files that are in both directories.  If you are
getting directory names in the output from ls, stick some awk code in
there...  awk -F/ '{print $NF}' ...that will take out the dir names.

If you have many pairs of directories to check, you can write a script
with a double for loop to get all pairs.
