I want to replace the useless "root(a)localhost" in my $PS1 by <consoleNumber>
How do users know which VT they are in, as they step from one to the
other, without remembering 'which button they pressed last time' ?!

OK, File: bashrc ==
# are we an interactive shell?
if [ "$PS1" ]; then
case $TERM in
xterm*)
PROMPT_COMMAND='echo -ne "\033]0;${USER}@${HOSTNAME}: ${PWD}\007"'
;;

And my prompt & the 3 evn-VARS are shown by:---
[root(a)localhost lsofTut]# echo $USER
eas <--- I su-ed to "root"
[root(a)localhost lsofTut]# echo $HOSTNAME
localhost.localdomain
[root(a)localhost lsofTut]# echo $PWD
/mnt/cdrom/Debug/lsofTut
-------------
But I dont know if/what to use to replace "HOSTNAME" to have PS1
show the VTnumber.
So, I'm seeing if/what env-VAR might show the VTnumber:-
# /usr/bin/printenv | grep onsol ==
KONSOLE_DCOP=DCOPRef(konsole-1279,konsole)
KONSOLE_DCOP_SESSION=DCOPRef(konsole-1279,session-3)

Where the "3" is the VT3 [of Desktop4]
So if my PS! replaced "root(a)localhost" with <3> that would be good.

Thanks, how would I do that ?
