In this Question the Question originally contained an incorrect command (
passwd password instead of
passwd username). My first Answer correctly answers the title ("How to change password in brand new Unix user") and addresses the question as it originally stood.
Through edits and comments, the real issue arose - the password didn't meet the requirements. Should a second Answer be posted with an explanation of the message
The password contains less than 1 digits? Should the existing Answer be appended? I think since the original Answer is a useful answer to "How to change password", so I think the original Answer's content should be preserved.
