copy/move files on remote server linux
<p>I log into <code>server_a</code> and run <code>.sh</code> file, which has the following script:</p>

<pre><code>scp user@server_b:/my_folder/my_file.xml user@server_b:/my_new_folder/
</code></pre>

<p>to copy files from <code>my_folder</code> to <code>my_new_folder</code> at <code>server_b</code>.  It doesn't throw an error, but no files are copied.</p>

<p>Notes:</p>

<ul>
<li><code>server_b</code> is accessed by the pre-set rsa_keys.</li>
<li><code>server_a</code>: unix </li>
<li><code>server_b</code>: ubuntu</li>
<li>can SCP files from/to these servers without any issues</li>
</ul>

<p>The end goal is to move or copy/remove files.</p>
