mutt -s "SUBJECT" -a file.pdf -c copy@me.com to@you.com < /tmp/ascii

This worked. - text in '/tmp/ascii' would show up in the body
- file.pdf is attached.
- no interaction

I'm now going to tackle doing a loop where multiple 'file.pdf' files
are attached to ONE email.

Please forgive me for the early (unnecessary) post.
