Hm, maybe I should include runvc and getvc in the open package (which I
happen to maintain).

BTW, since you are already at the console, you don't need to use all this,
the following command will flip you breifly to a free vt and back, which
does clear the scrollback buffer (neat trick!):

open -s -w false

Excuse my naivete, but won't printing a bunch of blank lines clear it?

Thanks

if you have SVGATextMode installed, executing 'stm' will do it.

Another way:

runvc false

where runvc is the following script:

   #!/bin/sh
   # Run something on a VC, from X, and switch back to X when done.
   # GPL Joey Hess, Thu, 10 Jul 1997 23:27:08 -0400
   exec open -s -- sh -c "$* ; chvt `getvc`"

and getvc is compiled from the following source

   /* getvc.c
* Prints the number of the current VC to stdout. Most of this code
* was ripped from the open program, and this code is GPL'd
*
* Joey Hess, Fri Apr  4 14:58:50 EST 1997
*/
   
   #include 
   #include 
   
   main () {
 int fd = 0;
 struct vt_stat vt;
   
 if ((fd = open("/dev/console",O_WRONLY,0)) < 0) {
   perror("Failed to open /dev/console\n");
   return(2);
 }
 if (ioctl(fd, VT_GETSTATE, &vt) < 0) {
   perror("can't get VTstate\n");
   close(fd);
   return(4);
 }
 printf("%d\n",vt.v_active);
   }
   
   /* End of getvc.c */

This method automates the switching of VC and can be run from .logout
(if you run a csh).

I use this script for 'runvc mc' from inside X.

Echo four thousand spaces from .bash_logout?

How can I clear the scroll-back buffer when a use logs out (other than
changing tty's)?
