Which command is used to set a password for a Linux user?

• A. chpasswd
• B. passwd
• C. passwd -l
• D. pwgen

Answer: (B)

The main idea is how Linux handles changing or setting user passwords. The command to set a password is passwd. When you run it, it can work in two common ways: - For your own account: running passwd prompts you to enter your current password, then the new password twice to confirm it. This is the typical way a user updates their own password. - As the superuser for another user: running passwd followed by a username lets you set that user’s password. It will prompt you to enter the new password for that account, even if you don’t know the current one. The other options don’t fit this exact need. chpasswd is used in scripts to update passwords in bulk (usually from a file), not for interactive password setting. pwgen is a password generator, producing random strings rather than actually applying them. passwd -l locks the password so the account can’t log in, which is about disabling access rather than setting a new password. So, for setting or changing a password in Linux, the command to use is passwd.
