Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

OTOH, if this is actually a homework lab it may(?) be ok.
Think I'm going to ask the Mods..
To the OP: I'd like to see clarification on the background of
this exercise/ hear from you what the justified objective might
be. Until such time as you provided this I ask our members to
refrain from responding to this thread (wonder how many will
actually read this rather than barging in w/ an answer).
I'll jump in and answer this, but it isn't going to help anyone subvert the password machinery. What you must have realized before you embarked on this little journey is that someone before you might have thought of your scheme, and of course you're right. The people who wrote the passwd tool were also smart enough to predict that there would be people like you, and made the tool so it does not read its input using standard IO, or at least did it in such a way that it requires actual keystrokes to enter the data. As such, it isn't subject to the perils of covert redirection, such as you've tried here. My hunch is that learning that might just be the point of the lesson.
