Which command initiates a password change on a Linux system?

• A. chpasswd
• B. change-password
• C. passwd
• D. userpasswd

Answer: (C)

The command used to initiate a password change on a Linux system is the standard interactive tool for updating passwords. When you run it without specifying a user, it prompts you to enter your current password for authentication and then asks you to enter a new one (and confirm it). If you have administrative privileges, you can provide a username to change someone else’s password, and the tool will prompt for the new password for that user. This interactive flow and the ability to affect either your own account or another user’s make it the correct choice for starting a password change. Other options don’t fit this scenario: one is meant for bulk updates in scripts rather than interactive changes, and the remaining two aren’t standard Linux commands for changing passwords.
