I concur with Nicolas: every time you say "folder", a unicorn dies. You mean: the union of dest-dir-1 and dest-dir-2 should equal your source-dir? Try rsync -a source-dir/ dest-dir-2/ --compare-dest=dest-dir-1/ This one will even dutifully copy those files from source-dir which can't be found either in dest-dir-1 or in dest-dir-2. If you only want to /see/ what would be copied (always a good idea when trying untested advice from random folks on the internets :) there's the option --dry-run. Perhaps add the option -v. Rsync is magic. Cheers -- t
