How do I prevent emacs from inserting a here document:
<<EOF

EOF
whenever I type <<
?

Type C-q before the second < to insert it literally.

This is controlled by sh-electric-here-document-mode, so disable
that minor mode to disable the automatic here document insertion.

Mr. Moreton's answer is the right one. Here's how I do it in my .emacs:

(eval-after-load "sh-script"
  '(add-hook 'sh-mode-hook '(lambda () (sh-electric-here-document-mode 0))))

Good catch. That much a much younger lisp programmer. I've already registered that as a bug.

I assumed you just wanted to disable it only in the rare cases where 
you're typing << that isn't the beginning of a here-doc. If you want to 
disable it totally, the other answer says how.
