Environment vars calling programs

[Don Harrop]

Damn, I hate syntax!  ;-)  That's what I get for playing with Linux boxes
that have always set stuff up like that for me..  I've got a couple other
questions that might be pretty easy too..  Basically what I want to do is
create a prompt that displays the username@hostname:pathname like you get
in most Linux installs.  With that last tid-bit I can set the prompt to
print everything I want until I su.  The username doesn't follow the user.  
I'm setting USER=`whoami` and using $USER in PS1 to get the username.  
I've also used `whoami` directly in the PS1 var.  No luck.  Is that
because the su program on HP-UX isn't designed to update any env vars?  
I'm setting all this up in the global config files so whoever I log in as
gets this setup but as soon as you su to anyone else it seems like it
looses the environment variable info.  Also when telneting in I have to
use ctrl H to backspace.  I've set ERASE='^H' and that doesn't seem to
help.  Do I have to use the escape code?  The environment is HP-UX 10.20
and I'm running a standard POSIX shell.
