-->Hallo everyone :
-->I'm trying to use setterm -append to dump my screen for report, but
-->everytime I try ,I got the message "can not ioctl dump" and left a zero size file
-->"screen.dump" on my directory. Could anybody kindly tell me why?
-->Thanks in advance.
Because in the "newer" kernels the ioctl has been changed to be a character
device of major 7. So this means you should be just able to use "cat" to
read the contents of a screen, e.g.
cat /dev/vcs1 >/tmp/screen
cat /dev/vcs2 >>/tmp/screen
P.s. install the manpages version 1.9 and then do
