Linux Process Hunter

If I run the script sometimes I get one hidden udevd process:

  $ sudo ./prochunter.py -r

  [!] Found 1 hidden process

  PID	Name

  $ sudo ./prochunter.py --ps | grep udev
  286	systemd-udevd
  24357	systemd-udevd
  $ sudo ./prochunter.py --ps | grep udev
  286	systemd-udevd
  $ sudo ./prochunter.py -r
