[Message part 1 (text/plain, inline)]

Hi Team,

In Linux system, I have created /tmp/123 directory.
---snip---
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 <at> test~]$ ssh user1 <at> testsh -c  'cp -vPprf /tmp/123 /tmp/4576'
user1 <at> 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
