Sure. I have:
HOST=`hostname`
NORMAL="\[\e[0m\]"
RED="\[\e[1;31m\]"
GREEN="\[\e[1;32m\]"
if [[ $EUID == 0 ]] ; then
PS1="$RED\u$NORMAL@$HOST$RED [ $NORMAL\w$RED ]# $NORMAL"
else
PS1="\u$GREEN@$HOST$GREEN [ $NORMAL\w$GREEN ]\$ $NORMAL"
fi
I use that for each user.
Note that ~/.bashrc does not get called when doing a normal login prompt unless
you specifically call it in ~/.bash_profile. That is not a part of the BOOK's
login script. To force a login prompt, use `/bin/bash -l`
~/.bashrc is normally called when bash is called interactively (forced by
/bin/bash -i)
