Question

What is the purpose of the chroot command?

(A) To change the root directory of the system.
(B) To confine a process to a specific directory.
(C) To change the user ID associated with a process.
(D) To change the group ID associated with a process.

Answer 1

The chroot command is used to confine a process to a specific directory, isolating it from the rest of the system. This can enhance security and is useful in development and testing scenarios.

Step-by-step explanation:

The purpose of the chroot command is to change the root directory of a running process so that it cannot access files outside of a designated directory tree. This effectively confines the process to a specific directory and its subdirectories, creating a confined space that isolates it from the rest of the system. This technique can be used to enhance system security by limiting the scope of potential damage that can be caused by rogue processes or users. It can also be useful in software development and testing when simulating an environment with a different root directory or when isolating software dependencies is necessary.

So, the correct answer to the provided question is (B) To confine a process to a specific directory.
