You run "ls" (or suchlike) to generate a list of directories names.

Then you use sed or something on the list, then you run a shell script over the
result to make "mv" commands to rename things.

Aside from your detailed "reverse my renaming" steps, have you considered just
brute force removing the duplication because you know the shapes of the
filenames.

If so, consider my "frename" script:

https://bitbucket.org/cameron_simpson/css/src/tip/bin/frename

(grab the "Raw" link at top right to download)

Then you can issue commands like this:

frename 's/2009}«{2009//g' *2009*2009*

or, given the regularity of your filenames:

frename 's/^(\d\d)«{(\d\d)}«{\d\d«{(\d\d\d\d).*/Pictures«Photos«$3-$1-$2/' *

Just an idea.

But FIRST, as a suggestion, take a copy of your tree (as almost zero cost!)

Of all your folders are in some superfolder called "foo" (for example), go to
above the superfolder and say:

cp -arl foo foo-NOT-RENAMED

This will make "foo-NOT-RENAMED" the same shape as your existing "foo" and with
all the files inside hardlinked, so not extra storage. Very fast and cheap.

Then if the renaming is a disaster, you can start again.

Ok, I used the following in my Pictures folder:

cp -arl * ../Temporary/DONE

Now, from what little I see, this works on files and not folders ???
