Slight modification from Alex's post:

for file in $(ls --color=none 2/); do cp 1/$file 2/$file; done

The --color=none might not be necessary, but it was for me. The $ in
front of the file inside the loop is definitely necessary.

I would make backups of both directories before you do something you can't undo.
