When I tried strace with /bin/cp -pi I can see on both commands
something like this:
utimensat(4, NULL, [{tv_sec=1588174263, tv_nsec=908624390} /*
2020-04-29T11:31:03.908624390-0400 */, {tv_sec=1486350336,
tv_nsec=481422339} /* 2017-02-05T22:05:36.481422339-0500 */], 0) = 0
The utimensat is exactly the same for both cp -pi to a ext4 file system
or to a smb filesystem. So, cp seems to be working as expected. Probably
the same is true to /bin/mv.
-----------------------------------------------------------------
Exactly the same behavior for /bin/cp and /bin/mv. I do not have any other cp or mv in my path.
$ sha1sum /bin/cp /bin/mv
220687a082fb9d0dbb48e9a2b1093cbb4e9de55a /bin/cp
46e71d67df7eb1c41f8f8c9039f401e242cce94a /bin/mv

First, do you see the same behavior if you use /bin/cp and /bin/mv
instead of simply cp and mv?
