Solution

The purpose of the /etc/sudoers file in Linux is to contain a list of users who are allowed to run certain commands as the root user. This is option c in your question.

Here's a step-by-step explanation:

  1. The /etc/sudoers file is a configuration file for the sudo command. The sudo command allows users to run programs with the security privileges of another user (by default, the root user).

  2. The /etc/sudoers file controls who can run what commands as what users on what machines and can also control special things such as whether a user needs to input their password when executing a particular command.

  3. The file is edited using the visudo command. This command opens a text editor with the current sudoers file and performs syntax checking on the file when it is saved, reducing the chance of misconfiguration.

  4. If a user is not listed in the sudoers file but tries to execute a command with sudo, they will receive an error message.

So, the purpose of the /etc/sudoers file in Linux is to manage the sudo privileges of different users on the system.
