Is there a way to use rsync to copy all the contents of one folder into another folder, but not the folder itself? That is, if I have a bunch of stuff in Folder_A, I want to copy all that stuff into Folder_B, but directly into Folder_B, not into a folder inside Folder_B that is named "Folder_A". And I want to use Folder_B as a backup location, so a simple cp command won't do the trick; it should work with rsync or a similar tool.
Any ideas? Thank you in advance.
