Hi Bob

thanks for the fast reply!
I did the following on Redhat-7.3 and Scientific Linux 304 (which 
reflects Redhat EL3 U4)

$ rpm -q -f /usr/bin/install
fileutils-4.1-10.1
-------------------------------------------------------------------
$ install --version
install (fileutils) 4.1

The man page says:

       -C     Install  file,  unless target already exists and is
              the same as the new file, in which case the modifi-
              cation time won't be changed.
-------------------------------------------------------------------
'install --help'  does not mention the option '-C'
-------------------------------------------------------------------
The following example reports the copy task, since the destination file 
does not exist....
$ install -Cv file /tmp/
`file' -> `/tmp/file'

... the second time, it does not (which is good).
$ install -Cv file /tmp/

Using just '-C' without '-v' does the job too, but never reports the 
action (good)
$ install -C file  /tmp/

$ rpm -qf /usr/bin/install

$ install --version
install (coreutils) 4.5.3

Even though option '-C' is never mentioned in 4.5.3, it still works as 
in version 4.1 (hmmmm?)

$ install -vC file  /tmp/
`file' -> `/tmp/file'

... and it's silent the second time
$ install -vC file  /tmp/

.. and this also works silently
$ install -C file  /tmp/
