su/sudo and terminal PS1 [Solved]

When you run "su -" or "sudo -i" where does it get the settings for bash PS1?

And how do I change it?

You can change it in /root/.bashrc

I also was wrestling with this the other day because the .bashrc that doesn't seem to help when you login to a tty shell.  for that I had to add something like this to /etc/profile:

if [ "`whoami`" = "root" ]; then
    lpath="/root/bin"
    PS1="\[\e[31;40m\]\u:\w# "
else
    lpath="/home/`whoami`/bin"
    PS1="\[\e[32;1m\]\u:\w$\[\e[0m\] "
fi
export PS1
PATH="$lpath:/bin:/usr/bin:/sbin:/usr/sbin"
export PATH

(Yes, I left the red color on root open because I like all of root's text output to be in red.)

Also with sudo I think you need to add an env_reset to /etc/sudoers

Defaults env_reset,rootpw
