title: Multiple grep search/ignore patterns
body: <p>I usually use the following pipeline to grep for a particular search string and yet ignore certain other patterns:</p>
  
  <pre><code>grep -Ri 64 src/install/ | grep -v \.svn | grep -v "file"| grep -v "2\.5" | grep -v "2\.6"
  </code></pre>
  
  <p>Can this be achieved in a succinct manner? I am using GNU grep 2.5.3.</p>
