递归比较Linux系统A上的根目录和Linux系统B上的根目录

Question

我试图使用rsync和ssh来区分两个Linux系统上的所有文件，方法是使用-运行选项，这样它就不会同步任何文件/文件夹。我做错了什么？运行此命令时，我当前位于根目录中。

命令：

rsync --dry-run -v 'ssh -p 22' root@192.168.86.128:/

输出：

[root@localhost /]# rsync --dry-run -v 'ssh -p 22' root@192.168.86.128:/

Answer 1

这在将系统A与系统B进行比较时起作用。

rsync --dry-run -r root@192.168.86.129:/ /

在将系统B与系统A进行比较时，这是有效的：

rsync --dry-run -r root@192.168.86.128:/ /
