How would you do that (in a portable manner)? I think this could be
privacy-relevant sometimes.
I have the following snippet in my .bash_logout for similar reasons:
#------------------------------------------------------------------------------
# When leaving the console clear the screen to increase privacy.
# Also clears the scroll-back buffer.
#------------------------------------------------------------------------------
case "$(tty)" in
/dev/tty[0-9])
t=$(v=`tty` ; echo ${v##*ty})
clear
chvt 63; chvt "$t"
;;
/dev/tty[0-9][0-9])
t=$(v=`tty` ; echo ${v##*ty})
clear
chvt 63; chvt "$t"
;;
*)
;;
esac
