What does the command usermod accomplish?

• A. Add a new user
• B. Remove a user account
• C. Change an existing user's configuration
• D. Display user account status

Answer: (C)

The command `usermod` is specifically designed to make modifications to an existing user's configuration in a Linux system. This could include changes like updating the user's home directory, changing the user's shell, adding the user to groups, or altering user privileges. The versatility of `usermod` allows system administrators to manage user accounts effectively without having to create new ones or delete existing ones when changes are needed. In contrast, other commands serve different purposes: adding a new user is typically done with the `useradd` command, while removing a user account is handled by the `userdel` command. To view user account status, the `id` or `getent` commands are commonly utilized, providing information about groups and user IDs without modification capabilities. Thus, the correct understanding of `usermod` focuses on its role in changing the configuration of existing user accounts.
