      I’m seeing in the Linux + book by CompTia that it’s 10 so to pass the exam, that’s fine, but why do other sites say the default is 0:

   Hi Che:

   Sorry, but default nice is 10. You can check:
   #nice top

   You will see 10 in the NI(nice) column

   Regards

      More or less you’re right. Default nice is +10, it’s 10 added to whatever is inherited from parent process, usually 0. But if it wasn’t 0, the value would be not ten but whatever it is +10.
