Well, this is where you have to get creative. By definition, an su
will not change $USER. So, you have to find a more clever way of
getting the username into the echo statement. Here's a cheap hack:
If you have it set up that the home directory of each user is it's
name (for the users you plan on su-ing to anyway), then you can use
the end of the $HOME variable as the user name. i.e.,
PROMPT_COMMAND='echo -ne "\033]0;${HOME##*/[EMAIL PROTECTED] : ${PWD}\007"'
That will strip off all the longest match from the beginning of $HOME to /.
Really, though, this is a crappy solution. Unless you spend a long
time in su, I don't see why this is a big problem. And if it is a big
problem for you, maybe you should just remove ${USER} from
PROMPT_COMMAND. It was just an example anyway.
