This results in PROMPT_COMMAND being set to "history -a; history -a"
after using su. It is added for the initial login and again for the root
login. However, "PROMPT_COMMAND="history -a" seems to work, as I don't
use PROMPT_COMMAND for anything else.
echo $PROMPT_COMMAND | grep -q history\ -a || export PROMPT_COMMAND...
should take care of it in a more general case.

You also want to set,
export PROMPT_COMMAND="${PROMPT_COMMAND:+${PROMPT_COMMAND} ;} history -a"
in cojuction with histappend.

I have not tried it but, for example my /etc/inittab has a line: ca:12345:ctrlaltdel:/sbin/shutdown -h now I am guessing that you could replace the shutdown command with a script of your own that does whatever you want, and then finally calls shutdown ? -- Simon Kellett,| Gentoo Linux, Fvwm, Firefox Darmstadt, Germany| Xemacs, Vm, Gnus -- gentoo-user@gentoo.org mailing list

Yes, but is there someway that when i press ctrl-alt-del that before Linux goes
in the process of reboot he previously log outs and then he goes in the process
of reboot?

check out also the history command in bash ('help history'). it has some
commands to write or append the current history to a file (I never used
it, just looked at the man page).
if it works you can have alias to 'history -a $HISTFILE
&& /sbin/reboot'. of course you have to check the history options.
