Hi Team,

In Linux system, I have cr= eated /tmp/123 directory.
---snip---
mkdir -p /tmp/123---snip---

/tmp/4576 is a non existent directory, now I am executin= g following cp command
---snip---
cp -vPprf /tmp/123 /tmp/4576
`/t= mp/123' -> `/tmp/4576'


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

So above command is successfully copied di= rectory 123 under /tmp/4576

Now I am trying to execute th= e same command over ssh

----snip---
[user1@test~]$ ssh= user1@testsh -c=C2=A0 'cp -vPprf /tmp/123 /tmp/4576'
user1@test= 's password:
cp: missing file arguments
Try `cp --help' for m= ore information.
----snip---

but it's always faili= ng. I have tried the same command on multiple Linux system and found same f= ailure.

Can you please help me why it's failing?

Is it a bug with cp -P option?
Are there any workar= ound mean any kind of configuration change is needed to get it work?

Hi Team,

Last time in my email one space was missing and = that lead to confusion I guess. I am very sorry for typo.

The c= p command I tried to execute over ssh

----snip---
[us= er1@test ~]$ ssh user1@test=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 sh -c=C2= =A0 'cp -vPprf /tmp/123 /tmp/4576'
user1@test's password= :
cp: missing file arguments
Try `cp --help' for more information= .
----snip---
last time by mistake I missed space between = ssh user1@test and sh -c=C2=A0 'cp -vPprf /tmp/123 /tmp/4576'
but it's always failing. I have tried the same command on multi= ple Linux system and found same failure.


I dig into furthe= r following are the observations

---snip---
[user1@tes= t ~]$ which cp
/bin/cp

[user1@test ~]$ cp --version

Then I execute
[user1@test ~]$ ssh user1= @test sh -c=C2=A0 "'which cp; cp -vPprf /tmp/123 /tmp/4576'&q= uot;
user1@test's password:
/usr/local/bin/cp
cp: W= arning: the meaning of `-P' will change in the future to conform to POS= IX.
Use `--parents' for the old meaning, and `--no-dereference' = for the new one.
/tmp -> /tmp/4576/tmp
`/tmp/123' -> `/tmp/= 4576/tmp/123'


[user1@test ~]$ /usr/local/bin/cp --version=

So from the above observation it's = very clear the problem is while trying to execute cp command over ssh then = it's taking /usr/local/bin/cp instead of
/bin/cp whic= h is causing the problem.


But in PATH e= nv variable /bin is preceding /usr/local/bin
[user1@test = ~]$ echo $PATH
/usr/lib64/qt-3.3/bin:/usr/kerberos/bin:/bin:/usr/bin:/usr/dev_infra/platform/bin:/usr/dev_infra/generic/bin:/usr/l= ocal/bin:/usr/X11R6/bin:/usr/local/ade/bin:/scratch/user1/bin
=

Even I checked in over ssh in PATH /bin appearing befor= e /usr/local/bin
[user1@test ~]$ ssh user1@test=C2=A0=C2= =A0 sh -c=C2=A0 "'echo $PATH; which cp; cp -vPprf /tmp/123 /tmp/45= 76'"
user1@test's password:
/usr/lib64/qt-3.3/bin:/u= sr/kerberos/bin:/bin:/usr/bin:/usr/dev_infra/platform/bin:/usr/dev_i= nfra/generic/bin:/usr/local/bin:/usr/X11R6/bin:/usr/local/ade/bin:/s= cratch/user1/bin
/usr/local/bin/cp
cp: Warning: the meaning of= `-P' will change in the future to conform to POSIX.
Use `--parents&= #39; for the old meaning, and `--no-dereference' for the new one.

Can you please give me any pointer why over ssh cp command= is taking /usr/local/bin specific executable rather than /bin specific executable?

Is there any way to force t= he cp command to take /bin specific executable over ssh?

Thanks in advance.
