D.
ps ---ef I grep 2274
Answers
D.
ps ---ef I grep 2274
Suggested answer: A

Explanation:

The renice command is used to change the priority of a running process by specifying its PID and the new nice value. The -n flag indicates the amount of change in the nice value, which can be positive or negative. A lower nice value means a higher priority, so -15 will increase the priority of the process with PID 2274. The administrator needs to have root privileges to do this.

The renice command is listed as one of the commands to manipulate process priority in the web search result1.

The renice command is also explained with examples in the web search result2.

The CompTIA Linux+ Certification Exam Objectives mention that the candidate should be able to ''manage process execution priorities'' as part of the System Operation and Maintenance domain1.
