Hi,
this should be trivial, but how can I clear an eshell buffer
(something similar to 'clear' command in many shells)?

Thanks,
Luca

You can write a function to do what you want.

--8<---------------cut here---------------start------------->8---
(defun eshell/clear ()
      "Clear the eshell buffer."
      (interactive)
      (let ((inhibit-read-only t))
        (erase-buffer)))
--8<---------------cut here---------------end--------------->8---

It's a bad trip but I'll take it.

I don't know, but you don't need that. You get crazy
clearing the screen all the time. Accept there are old
commands and data there, learn to focus on the new
task still. It helps :)

There is C-c C-o eshell-kill-output which clears the output of the
last command.  Not perfect but it has been standard for a long time.

[I don't usually use eshell but I use the regular shell mode all of the
time.  In the regular shell if I want to clear the buffer I run C-x h
to mark the entire buffer and C-w to cut all of it and then Enter to
get a prompt back again.]

C-c C-t will truncate the buffer to leave just
eshell-buffer-maximum-lines lines.

Based on that, you can do :
(defun luca/eshell-clear-buffer ()
  (interactive)
  (let ((eshell-buffer-maximum-lines 0))
    (eshell-truncate-buffer)))

In terminal emulators, `clear` does not erase the content of the window;
`clear` just moves the current line to the top of the window. In Emacs,
this can be accomplished with:
