title: removing ^M from a csv file
body: <p>I have a problem when I try to remove ^M from a csv</p>
  
  <p>When I type vim or vi file.csv, I get</p>
  
  <pre><code>A, TK,2015-04-06,14.4^M,14.7,10.0,0.0,54.0^M,13.3^M,135.0^M,33.8
  B, NV,2015-04-06,14.4^M,14.7,5.4,0.0,47.0^M,14.8^M,97.0^M,31.3
  </code></pre>
  
  <p>I have tried with </p>
  
  <pre><code>tr -d '^M' &lt; file.csv &gt; file2.csv
  </code></pre>
  
  <p>But it doesn't remove, also with sed.</p>
