Syncing Directories Between Mac and Windows

Mac

$ cd path/to/parent/of/directory/to/be/synced/
$ rsync -a /Volumes/share/path/to/src/ src

The -a flag is recursive, and it preserves permissions.

To preview the operation, use the -n (dry-run) and -v (verbose) flags:

$ rsync -anv /Volumes/share/path/to/src/ src
