00:00:06,690 --> 00:00:08,910
- All right, let's do a lab.

2
00:00:08,910 --> 00:00:11,880
From a root shell, start three processes

3
00:00:11,880 --> 00:00:14,160
dd if=/dev/zero of=/dev/null

4
00:00:14,160 --> 00:00:17,010
which are just generating a lot of work.

5
00:00:17,010 --> 00:00:18,780
Use the appropriate command to show

6
00:00:18,780 --> 00:00:20,970
that they are running as expected,

7
00:00:20,970 --> 00:00:22,680
then change process priority

8
00:00:22,680 --> 00:00:24,300
so that one of these three jobs

9
00:00:24,300 --> 00:00:27,120
gets double the amount of CPU resources,

10
00:00:27,120 --> 00:00:28,860
and monitor the processes are running

11
00:00:28,860 --> 00:00:31,743
as expected and then
terminate all of them.
