title: Does grep function detect tab delimiter?
body: <p>I've got a question here.
  I have a raw file A which contains the column as below:</p>
  
  <pre><code>LG111222332626 2626 T C G A
  
  LG111222332626 467789 G C G G
  .....
  </code></pre>
  
  <p>The column are separated by delimiter "TAB".
  My question is How to retrieve my desire line from raw file A if i were given a list B like as below:</p>
  
  <pre><code>LG111222332626 2626 
  
  LG111222334768 1212
  .........
  </code></pre>
  
  <p>I was wondering if grep function able to do something like this </p>
  
  <pre><code>grep -e "LG111222332626\t2626" 
  </code></pre>
  
  <p>(but grep seems doesn't recognised <code>\t</code> here, what is the proper way to do this.)</p>
  
  <p>Thanks all. Sorry if the way i express my problem is a bit confusing, hope you read me =)</p>
