title: RegEx for "does not begin with"
body: <p>The following checks if it begins with "End":</p>
  
  <pre><code>if [[ "$line" =~ ^End ]]
  </code></pre>
  
  <p>I am trying to find out how to match something that does not begin with "02/18/13". I have tried the following:</p>
  
  <pre><code>if [[ "$line" != ^02/18/13 ]]
  
  if [[ "$line" != ^02\/18\/13 ]]
  </code></pre>
  
  <p>Neither of them seemed to work.</p>
