Shells like zsh and bash also clear the screen while you are typing a line. So your solution works only fine at the start of a line. And adding a c-g or c-c won't help since it also interupts the macro. # Han

I tried to do something like that : bind -m ^L=^Uclear^M^Y If you do each steps one by one, it works: remove the line, use clear and put the line back on the screen. For some reason once it's in the bind, it doesn't 'use' the ^Y at the end. In fact if you ^Y by hand after this user-defined ^L, it 'pastes' the non-empty line that was there before the clear. -- Bertrand

Please note that when using emacs editing mode (I think this is the
default mode, unless you set VISUAL=vi or use `set -o vi` explicitly)
and when in command-mode in the vi editing mode, ^L is already bound
to redraw. This will redraw your current input line. See ksh(1) for
more info (search for \^L). But anyway...
What is wrong with using clear ? You could alias it to l or L or
create a function of the same name in your shell configuration file
(.profile) to have the same effect with the same number of keypresses.
Using an alias :
alias l=/usr/bin/tput clear
alias L=/usr/bin/tput clear
Using a function :
l() { /usr/bin/tput clear; }
L() { /usr/bin/tput clear; }
You could also try this in your shell :
trap '/usr/bin/tput clear' 2
And press ^C. Note that this has some rather unfortunate side-effects
(apart from being silly), but it does does clear the screen on ^C.
A last option would be to send a patch for ksh that adds a clearscreen
command to bind to. Send it here and it'll probably get more attention
from developers. This is left as an excercise to you ;)
Good luck clearing your screen !

This is left as an excercise to you ;) This would require linking ksh to libtermcap, growing it substantially. The genius of ksh's line editor is its simplicity: it just uses carriage return to overwrite the line, it doesn't do full cursor control. -- Christian naddy Weisgerber [EMAIL PROTECTED]

That's probably not what the original The alias is in .kshrc. I just it CNTL-L on the command prompt and the screen will be cleared. Just try it. If it doesn't work for you (in ksh) then we must have some different settings for it. poster asked for, given the mention of bash. Sorry, my reply was prompted by to your statement: ! You can't, at the shell prompt. ksh can't do that. It works under SunOS 5.8 et.al. too.
