body: <p>I'm trying to make a copy of one directory files into another directory. </p>
  
  <p>I have Desktop/projectOne and Desktop/projectTwo and I'm trying to copy projectOne files into projectTwo. I need to use terminal for this as I need to copy hidden files also and I'm not familiar with linux commands...</p>
  
  <p>So my question is...</p>
  
  <ol>
  <li><p>What commands do I have to use to copy all files (hidden files included) from Desktop/projectOne to Desktop/projectTwo?</p></li>
  <li><p>What commands do I have to use to copy only hidden files from Desktop/projectOne to Desktop/projectTwo?</p></li>
  </ol>
  
  <p>Thanks in advance.</p>
