我在一台机器上有一个源目录,其中有一堆文件,都具有相同的权限,我想复制到另一个目录,通过SMB挂载.

目标目录是通过SMB安装的,我试图一次性复制这组文件.

请注意,前两个文件的时间和权限与源目录中的时间和权限相同,但其余文件的时间和权限不同.
因此,似乎我可以复制一些文件并保留其权限和时间,但不能保存其他文件,即使所有源文件来自同一个地方并具有相同的权限和(或多或少)次数,而且我m同时将它们全部复制到同一目录 – 因此使用相同的umask等.
那么,为什么我可以保留一些但不是所有文件的时间？
我很乐意提供更多细节(umask,Linux版本,smb.conf等),除了我无法理解这些细节如何解释我所看到的 – 因为它们应该在这里不变.
