title: grep to find a string, get the line before and after with no line numbers displayed
body: <p>Recently I had a need to search for a particular string in a file and I needed to display the line before and the line after the match.</p>
  
  <p>File </p>
  
  <pre>
  AAAA
  BBBB                      
  CCCC
  DDDD
  </pre>
  
  <p>Using google I found the following solution utilizing grep.</p>
  
  <pre><code>grep -n1 BBBB File
  </code></pre>
  
  <p>Which outputs,</p>
  
  <pre><code>1-AAAA
  2-BBBB
  3-CCCC
  </code></pre>
  
  <p>So this does what I want except it displays the line numbers in the output.</p>
  
  <p>Is there a way to suppress the line numbers?</p>
