====== CPU Priority ======
Nice is used to set CPU priority.  

Niceness runs from 
  * -20, the highest priority, lowest niceness, to 
  * 19, the lowest priority, highest niceness and
  * Zero is the default

Yes, this is a bit counter-intuitive.

To reduce to **lowest** priority for user ''batadmin''
<code bash>
renice -n 19 -u batadmin
</code>
Response
<code>
45100: old priority 0, new priority 10
</code>
**Note**: New processes will get the default priority.

To increase priority mid-way to user ''wasadmin''
<code bash>
renice -n -10 -u wasadmin
</code>
