title: Grep after and before lines of last Match
body: <p>I am searching through few logs and I want to grep the last match along with it's above and below few lines.</p>
  
  <p><code>grep -A10 -B10  "searchString" my.log</code> will print all the matches with after and before 10 lines
  <code>grep "searchString" my.log | tail -n 1</code> will print the last match.</p>
  
  <p>I want to combine both and get the after and before 10 lines of last match.</p>
