Running Ubuntu 20.04 and want to compare two directories called 1 and 2 and move differences to a separate directory called 3, ideally conserving the subdirectories.
I am able to get almost the desired effect using:
rsync -aHxv --progress --compare-dest="$PWD"/2 1/ 3/
except that it copies the files instead of moving them.
I've also tried other answers from a similar question here, but the goal there is to copy, not move, and it seems that using mv doesn't conserve the subdirectories.
