Oops... reading this more carefully, it sounds like you want to generate 
the md5sums of all the files in the whole tree, not just a given 
directory. In that case, you need a bit more firepower:


for i in `ls -R /dir | perl -e 'while(<STDIN>){if($_=~/(.+)\:$/){print 
"$1\n";}}'`; do
        for j in $i/*; do
                md5sum $j >> md5sums.list
        done
done


Gross, but it will get the job done. Sorry for misunderstanding. ;)
