title: adb bugreport: Is there a way to reset the log?
body: <p>Hey, I'm new to Android/ADB</p>
  
  <p>I've been asked to dump an adb bugreport log by someone.  I managed to do this, but the report was 640k and had a ton of crash dumps for various apps that I was playing with.  I'm trying to present just the information for the app we're interested in.</p>
  
  <p>Is there a way to reset the log so that I don't have all this other cruft?</p>
  
  <p>thanks!</p>
