Question

In single user mode, the shell runs as which user?

1) Admin user
2) Root user
3) Normal user

Answer 1

In single user mode, the shell runs as the root user, allowing full system control and administration.

Step-by-step explanation:

In single user mode, the shell runs as the root user.

Single user mode is a troubleshooting mode in operating systems, such as Linux and Unix, where only one user, the root user, has full privileges and control over the system. Operating in single user mode allows for system administration tasks, such as password recovery or system repairs, to be performed without any interference from other users or processes.

By running the shell as the root user, it grants the user unrestricted access to the system, enabling them to make changes and modifications to the operating system itself.
