title: CPU usage in top batch mode
body: <p>I have a problem that makes me mad. I am running top in batch mode with the following command,</p>
  
  <p><code>top -b -n 1</code></p>
  
  <p>The problem is I can run top in batch mode 100 times but the CPU usage never changes past the original value. The memory usage changes as expected but CPU stays the same. If I simultaneously run another top in a different window the CPU usage is changing for that top but not for the top in batch mode.</p>
  
  <p>Basically CPU stats don't seem to change in batch mode and do in interactive mode. Does anyone know why?
  Try it yourself, run the above command a few times and observe the CPU usage staying the same then run top in interactive mode and observe the CPU usage constantly changing.</p>
