shell problem in emacs

[Ronald]

I'm using a eshell in emacs.
Can I use ``clear"?
My .bashrc file doesn't work here, how to apply it to eshell?

No, it will not work.  One possible solution is to use recenter with an
argument of 0, then issue end-of-line.  One could get creative and
create a function that does the same thing.

(defun eshell-clear ()
  "Mimics the behavior of clear"
  (interactive)
  (recenter 0)
  (end-of-line))

That is a good question.  I tried to run 'source' at the eshell prompt,
but that did not work.  Have you looked in the manual?

An already posted solution is:

(defun kai-eshell-erase-buffer ()
  "Erase contents of Eshell Buffer."
  (interactive)
  (let ((eshell-buffer-maximum-lines 0))
    (eshell-truncate-buffer)))

And with:

(defalias 'eshell/clear 'kai-eshell-erase-buffer)

you type "clear RET" in an eshell-buffer and it behaves as expected.

What exactly do you want to have available in eshell? The aliases get
stored in ~/.eshell/alias and their syntax is a bit different.

When typing the same unknown command into eshell several times (3 or 4),
you get asked for an alias definition.
