How does single-user mode differ from multiuser mode?


How does the use of lock icons that require password authentication to open reflect the principle of least privilege?


What do the letters of the su command stand for? (Hint: It is not Superuser.) What can you do with su besides give yourself Superuser privileges?

How would you allow a user to execute privileged commands without giving the user the Superuser password?


Assume you are working as Superuser. How do you kill process 1648? How do you kill all processes running Safari?
