title: How to copy folders with 'gsutil'?
body: <p>I've read the documentation on the <code>gsutil cp</code> command, but still don't understand how to copy folders to keep the same permissions. I tried this command:</p>
  
  <pre><code>gsutil cp gs://bucket-name/folder1/folder_to_copy gs://bucket-name/folder1/new_folder
  </code></pre>
  
  <p>But it resulted with the error:</p>
  
  <pre><code>CommandException: No URLs matched
  </code></pre>
  
  <p>Although, when I tried it with slashes in the end of each name, it didn't show any error:</p>
  
  <pre><code>gsutil cp gs://bucket-name/folder1/folder_to_copy/ gs://bucket-name/folder1/new_folder/
  </code></pre>
  
  <p>However, there was no new folder in the bucket when I checked with <code>gsutil ls</code>. What am I doing wrong?</p>
