title: How to filter .exe files from text file
body: <p>This is an example line from the file:</p>
  
  <blockquote>
    <p>O4 - HKLM..\Run: [TkBellExe] C:\Program Files\Common
    Files\Real\Update_OB\realsched.exe (RealNetworks, Inc.)</p>
  </blockquote>
  
  <p>I just need <strong>realsched.exe</strong></p>
  
  <pre><code>egrep '^O4' file.txt | egrep '[[:alnum:]]{0,99}\.exe' 
  </code></pre>
  
  <p>Vague, but the closest thing that works. (Ignore the first grep, using that to find 4 lines)
  But when the exe file has characters such as <code>_</code> then it doesn't work.</p>
