  <pre><code>/hdfs/data/t11/t111/t1/t/z/InterfacePublique/

  <p>I need a hadoop command that can display only the line :</p>
  
  <pre><code>DIS_CD_RLT_PSE,I,,113424,6.6449394612410755
  </code></pre>
  
  <p>Given by <strong>DIS_CD_RLT_PSE</strong> and <strong>I</strong> string.</p>
  
  <p>I tried like this :</p>
  
  <pre><code>Hadoop fs -ls /hdfs/data/t11/t111/t1/t/z/InterfacePublique/ | grep DIS_CD_RLT_PSE | grep I
  </code></pre>
  
  <p>But it doesn't give the needed result.</p>
