Adduser only one or. two users

[Ishaan Mahajan <ishaanamahajan@gmail.com>]

Hi,

This is the line I have got - RUN sudo adduser --shell $USERSHELLPATH --disabled-password --gecos "" $USERNAME && \

echo "$USERNAME ALL=(ALL) NOPASSWD: ALL" > /etc/sudoers.d/$USERNAME && \

chmod 0440 /etc/sudoers.d/USERNAME

However, I keep getting the error, 

adduser: Only one or two names allowed.

How do I get around this?  

Have a great day ahead!

Best,
