title: moving a file with spaces in name
body: <p>I have a file in unix with name as "this is my file.xls"</p>
  
  <p>I want to move it from one folder to other. I wrote the below lines:</p>
  
  <pre><code>fileName="this is my file"
  myDate=20121125
  
  mv $FIRST_DIR/"${fileName}.xls" $SECOND_DIR/"${fileName}_${myDate}.xls"
  </code></pre>
  
  <p>However, this is not working. I am getting error as "file.xls is not a directory"</p>
  
  <p>What is the correct way to do this?</p>
  
  <p>Thanks for reading!</p>
