portion immediately after the $PWD


Thanks for the clarity guys. It took me a few minutes to see the matching
[]'s and to escape the correct ones. My syntax highlighting was confusing me
but I think my enemy is that I'm trying to use the [] characters in my
prompt and that they are also control characters here. But heres what I
ended up with and this works.
PS1='address@hidden;45m\]\h\[\e[0m\] $PWD\[\e]2;@ \H\a\]]\$ '

I was mainly concerned only with the system name in the title bar to help me
feel in a little more control in my window manager. But you are correct in
saying that my .bashrc workaround is not the proper way to handle my problem
since it does not handle a scenario where multiple logouts are performed
after a chain of logins.
