You are on the right track, assuming you *must* do this with DOS tools.
(After all, Unix-like fileutils can be gotten quite easily from SimTel
mirrors.) You should invoke the commands like above through a sub-shell,
like this:
command /c for %%filename in ($(files_to_move)) do move %%filename stage1
(note the double-percent chars).
Also note that not all versions of DOS have MOVE command, but if you are
only doing this for yourself, you don't need to be concerned about it.
For the compare step (which you will meet further down the line) you will
need cmp from GNU diffutils. If you want to do that step (it's optional)
be warned that some early DOS ports of it think all files on a DOS disk
are identical, so you might get incorrect reports.
