In Linux system, I have created /tmp/123 directory.

mkdir -p /tmp/123
---snip---

/tmp/4576 is a non existent directory, now I am executing following cp command
---snip---
cp -vPprf /tmp/123 /tmp/4576
`/tmp/123' -> `/tmp/4576'

ls /tmp/4576
123
---snip---

So above command is successfully copied directory 123 under /tmp/4576

Now I am trying to execute the same command over ssh

----snip---
[user1@test~]$ ssh user1@testsh -c  'cp -vPprf /tmp/123 /tmp/4576'
user1@test's password:
cp: missing file arguments
Try `cp --help' for more information.
----snip---

but it's always failing. I have tried the same command on multiple Linux system and found same failure.

Can you please help me why it's failing?

Is it a bug with cp -P option?

Are there any workaround mean any kind of configuration change is needed to get it work?

Thanks,

Kousik
