Where can you use the su command to change the root user in GNU/Linux?

Question

Select one:
a. shell prompt
b. host alias
c. user login

Answer 1

It's surly A.

Answer 2

You don't "change the root user". You can "change to the root user", but you can not change the root user.



a. shell prompt

Answer 3

My advice to you is if you have to ask on Yahoo answers for an answer to this question then you probably shouldn't be doing the subject the homework is for in the first place.

Answer 4

Who wrote that question? Su never changes the root user. Su means substitute user. It is only used at the shell prompt.
