  <p>I want to remove all strings before tab (include tab) in a line of text and print the output(example: 13201096 ) to standard out.</p>
  
  <p>Example:</p>
  
  <pre><code># egrep -i "Incoming_Queries_A:" ./1.txt | sed  's/.Incoming_Queries_A:\t//'
  </code></pre>
  
  <p>Output:</p>
  
  <pre><code>Incoming_Queries_A:     13201096
  </code></pre>
  
  <p>But I only want to output <strong>13201096</strong> </p>
  
  <p>How to fix it? thanks</p>
