Cygwin copy only if file already exists

I want to copy a xml file from one remote box to a bunch of other remote boxes, but I only want it to copy the file it there is currently an existing file already in place. How can I do that?

One more question, is there a way to export out the list of only if the file exists?

This will work from inside in a bash file:

if [ -f /path/to/file.xml ]; then
  cp /path/to/file.xml /path/to/other/file.xml
fi

A one-liner for the command line might be:

[ -f /path/to/file.xml ] && cp /path/to/file.xml /path/to/other/file.xml

I'm not sure about using cygwin but as it's windows you can just use xcopy.

xcopy \\remotebox1\file.xml \\remotebox2\file.xml /U /Y

That will copy the file only if it exists in the destination already, and will overwrite without prompting.

You can just do it using regular DOS commands, there's no need to resort to cygwin:

IF EXIST filename_on_remote_server COPY /Y filename_on_local_server filename_on_remote_server

Or, if you are writing a BASH script for cygwin, then you can refer to this answer.
