如何rsync到不同的目录？

这是我想要实现的目标：

运行 Rsync 以递归方式比较两个目录，如下所示：

rsync -r /source /target

但实际上并不在目录之间进行 rsync。我希望将产生的差异 rsyncd/复制到另一个 3. 目录。

有任何想法吗？

--compare-dest你的朋友在这里吗：

rsync -rvn --compare-dest /target/ /source/ /extra_target/

（确认适用后删除-v和-n）

这是一个显示它的 shell 会话：

dennis@lightning:~$ cd /tmp
dennis@lightning:/tmp$ mkdir rs1
dennis@lightning:/tmp$ touch rs1/f1
dennis@lightning:/tmp$ rsync -av rs1/ rs2/

./
