Yes, I do find this all extremely helpful and enlightening. Believe it or not, using sort did occur to me.
But you are right - for the immediate job at hand, renaming files is an unnecessary distraction. Unfortunately, I often get distracted with trying to order things - a symptom of my illness. On the other hand, I thought to keep the originals, and would like them to sort properly. But yes, let's leave that exercise for another time.
OK, since all directories are sorted into canonical order, and since all files have been renumbered with my little regex, this was all that was needed:
Code:
sort -n OTfilelist.txt > OTfilelistsorted.txt

They are now all in perfect order, so let's take a moment to grab a beer out of the fridge, and go back to your original instructions....

Code:
cat: Testament/21_Ecclesiastes/Ecclesiastes12.txt: No such file or directory
cat: Testament/22_Song: No such file or directory

As you can see, it lost Ecclesiastes12.txt because there's an unescaped space between Old and Testament. And it sees Song of Solomon as three different (non-existent) directories.
Also, changing the filenames in the list files was a bad idea. And in retrospect, it is clear why. So, find does not escape any spaces in filenames in it's print output. It's funny, if I just drag a file onto the Terminal, it shows the path with all spaces escaped. You would expect the opposite since drag & drop is such a Mac thing, while find is a real unix program.
Is it possible to simply pipe the stdout of find directly to cat? Perhaps that could eliminate the problem of how it prints paths? Or, better yet, pipe find to sort to cat? Am I over-estimating the omnipotence of unix? I have to admit, it's powerful one-liners that get me excited. It's what really drew me into wanting to learn unix in the first place.
Then again, it may pay to go ahead and fix the actual filenames first. Since it's 02:00 where I'm at, it may be best if I come back to it tomorrow.
