To apply it to everyone, copy-n-paste the following into /etc/bashrc,
otherwise into your $HOME/.bashrc and the prompt will be active next
shell you open, or into any window to make it immediately active:

export PROMPT_COMMAND='PS1=`if test "$UID" = 0 ; then \
echo "\[\033[01;31m\]\u@\h $(pwd)]#\[\033[0m\] " ; \
else \
echo "\[\033[01;34m\][\u@\h $(pwd)]$\[\033[0m\] " ; \
fi `'

The 31m is red for root's prompt; 34m is blue prompt for everyone not
root. Feel free to change them to whatever suits your eyes.

It is worth pointing out you can put this test logic in the
user's and root's .bashrc file and not use PROMPT_COMMAND.
Using PROMPT_COMMAND messes up the exit status, since
whatever command you think you ran last, you really
ran the echo in PROMPT_COMMAND. (This is not a problem
in a script, but can make interactive testing difficult.)
