rsync --delete-before -a- after writing the target directory H -v --progress --stats ./fordelete/ ./caches/
Parameter description:
-delete-before the receiver deletes before transmission
-progress displays the transmission process during transmission
-a archive mode, which means that files are transferred recursively, and all file attributes are
maintained -H keep hard-linked files
