emacs eshell, how to clear screen?

parv · 11-19-2009, 06:46 PM

While in eshell, how to implement the function such that when I type "clear" it will
behave as the "clear" in bash or tcsh? I am unable to find a good working way of doing
this by googling.

Thanks.

Parv,

I have no idea what eshell, is, but you might give a try at the alternate method of clearing a screen that works in bash -- that is, <ctrl>-L

<ctrl>-L is the ASCII character 0x0C, for "FF (NP form feed, new page)"

Thanks.
Actually, there is a function corresponding to Ctrl-L in emacs which does move screen in a cycle mode.
For instance, if I am at the bottom of the screen, the first time I hit C-l would move the screen half way up,
the second hit move it to the top. But as soon as I hit enter, I am at the bottom again with all the stuff
I just tried to hide/get rid of. In this case, i am not happy with the way C-l works.

found a pretty good example http://www.northbound-train.com/emacs/em-joc.el.
eshell/clear() is almost what I need, just added (eshell-send-input) at the end.
Now, it works as I wanted.
