If you want to emulate Control-L in Eshell (the Emacs Shell) like in Xterm, you can use this :

(defun eshell-show-minimum-output ()
  (interactive)
  (goto-char (eshell-beginning-of-output))
  (set-window-start (selected-window)
		    (save-excursion
		      (goto-char (point-max))
		      (line-beginning-position)))
  (eshell-end-of-output))

And add a key bind to it in your custom hook :

(local-set-key "\C-l" 'eshell-show-minimum-output)</p>
