Puts the contents of foo into /dest with no "foo" directoryįor the Mac OS X bundled rsync 2.6.9 you can use the following line to achieve the same, but with the extra speed of delta copy. In other words, each of the following commands copies the files in the same way, including their setting of the attributes of /dest/foo:Ĭopies "foo" itself to /dest directory creating a foo subdirectoryĬopies "foo/*" to /dest directory implicitely forcing the creation of "foo" at the destination You can think of a trailing / on a source as meaning "copy the contents of this directory" as opposed to "copy the directory by name", but in both cases the attributes of the containing directory are transferred to the containing directory on the destination.

While looking for the perfect product to keep my photos safe, I discovered that sometimes simple is best.
