title: Fastest way to find strings in a file
body: <p>I have a log file that is not more than 10KB  (File size can go up to 2 MB max) and I want to find if atleast one group of these strings occurs in the files. These strings will be on different lines like,</p>
  <blockquote>
  <p>ACTION:.......</p>
  <p>INPUT:...........</p>
  <p>RESULT:..........</p>
  </blockquote>
  <p>I need to know atleast if one group of above exists in the file. And I have do this about 100 times for a test (each time log is different, so I have reload and read the log), so I am looking for fastest and bets way to do this.</p>
  <p>I looked up in the forums for finding the fastest way, but I dont think my file is too big for those silutions.</p>
  <p>Thansk for looking.</p>
