eshell (which is a shell in elisp, rather than emacs access to the shell) can do an lot of this sort of thing. For example I have the following:

(eval-after-load "eshell"
  '(progn
     (defun my-eshell-kill-output ()
       "Really kill (not delete) all output from interpreter since last input.
Does not delete the prompt."
       (interactive)
       (save-excursion
         (goto-char (eshell-beginning-of-output))
         (insert "*** output flushed ***\n")
         (kill-region (point) (eshell-end-of-output))))

     (add-hook 'eshell-mode-hook #'(lambda ()
                                     (define-key eshell-mode-map (kbd "C-c C-o") 'my-eshell-kill-output)))))
