title: AWK Column match
body: <p>I am trying to find a column match with grep but with no luck
  Below is my DataSet</p>
  <pre><code>A1|B1|C1
  A11|B2|C111
  A1|B23|C97
  </code></pre>
  <pre><code>cat file|while IFS=&quot;|&quot; read -r A B C
  do
    x1=`egrep $A $file`. # here I want A1 should be matched to A1 but I am gettin A1/A11/A1 
  done
  </code></pre>
  <p>I want to compare A1 of 1st line 1st column to A1 of other line it can be 2nd/30th etc.
  So I want to compare column and row to column row.</p>
