title: input file is output file error
body: <p>I'm trying to run the command </p>
  
  <pre><code>find . -name "*.csv" | xargs -I{} cat '{}' &gt; Everything2.csv
  </code></pre>
  
  <p>and I get back:</p>
  
  <blockquote>
    <p>cat: ./Everything2.csv: input file is output file</p>
  </blockquote>
  
  <p>What does this mean? </p>
