title: AWS CLI S3 rm command does not produce error if file does not exist
body: <p>I have a bash script which iterates over an array of file names and removes them from S3. </p>
  
  <p>The following command:</p>
  
  <pre><code>aws s3 rm "s3://myBucket/myFolder/myFile.txt"
  </code></pre>
  
  <p>will produce this output.</p>
  
  <pre><code>delete: s3://myBucket/myFolder/myFile.txt
  </code></pre>
  
  <p>I can see that the delete was successful by verifying it has been removed in the AWS console.
  However if I iterate over the same list again, I get the same output even though the file is gone.</p>
  
  <p>Is there any way -- using just the rm command -- of indicating that AWS CLI tried to delete the file but could not find it?</p>
