title: Is it possible to get current CPU utilisation from a specific core via /sys in Linux?
body: <p>I would like to write a shellscript that reads the current CPU utilisation on a per-core basis. Is it possible to read this from the <code>/sys</code> directory in Linux (CentOS 8)? I have found <code>/sys/bus/cpu/drivers/processor/cpu0</code> which does give me a fair bit of information (like current frequency), but I've yet to figure out how to read CPU utilisation. </p>
  
  <p>In other words: Is there a file that gives me current utilisation of a specific CPU core in Linux, specifically CentOS 8?</p>
