great idea -- i'll have to snoop around in there for a while.
good modular solution! i've been using perl's Term::ANSIColor
module, which is really hard-wired cheat-code, but it works for
the most part.

here's my setup -- comments welcome.
# System-wide /etc/bash.bashrc file for interactive bash(1) shells.
umask 022
# If running interactively, then:
if [ "$PS1" ]; then
function makePrompt
{
local ESC='\e';
# control-O restores charset after 'cat <binaryfile>'
local CHARSET='\017'
# define USERCOLOR, ROOTCOLOR, SYSCOLOR, HOSTCOLOR
. /etc/bash.bashrc.local
local CHR='\$'
if [ "`id -u`" -eq 0 ]; then
USERCOLOR=$ROOTCOLOR
#PATH="/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games"
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11"
elif [ "`id -u`" -lt 1000 ]; then
USERCOLOR=$SYSCOLOR
fi
if [ "$BASH" ]; then
#PS1='[EMAIL PROTECTED]:\w\$ '
# get ANSI esc seq for colorization, and bracket
# with \[...\]
function bracket
{
local seq=`perl -MTerm::ANSIColor -e "print
color(qw/$*/)"`
echo "\[$seq\]"
}
USERCOLOR=`bracket $USERCOLOR`
HOSTCOLOR=`bracket $HOSTCOLOR`
local DECOLOR=`bracket RESET`
unset bracket
local LOGIN="[EMAIL PROTECTED]"
local WHERE="\w${DECOLOR}"
local WHEN="\[$ESC[\$LINES;\$((\$COLUMNS -
19))H\]${HOSTCOLOR}\d \t${DECOLOR}"
PS1="$CHARSET$LOGIN:$WHERE$WHEN\n$USERCOLOR$CHR $DECOLOR "
PS1=`echo $PS1 | sed -e 's/\\\\\\]\\\\\\[//g'`
else
PS1="[EMAIL PROTECTED] $CHR "
fi
set -
unset USERCOLOR ROOTCOLOR SYSCOLOR HOSTCOLOR
}
makePrompt
unset makePrompt
export PATH PS1
# set a fancy prompt (overwrite the one in /etc/profile)
#PS1='${debian_chroot:+($debian_chroot)[EMAIL PROTECTED]:\w\$ '
# check the window size after each command and, if necessary,
# update the values of LINES and COLUMNS.
shopt -s checkwinsize
# don't put duplicate lines in the history. See bash(1) for more options
export HISTCONTROL=ignoredups
# enable bash completion in interactive shells
if [ -f /etc/bash_completion ]; then
. /etc/bash_completion
fi
fi
and here's the /etc/bash.bashrc.local for modularity -- all i
change on different hosts is the HOSTCOLOR. so at a glance i can
see if i'm root (red) a sysuser (green) or a normal user (blue).
and after a few moments of use, i can get quite familiar with
which host i'm on as well.
# local settings for use in /etc/bash.bashrc
USERCOLOR="BOLD WHITE ON_BLUE"
ROOTCOLOR="BOLD YELLOW ON_RED"
SYSCOLOR="BOLD YELLOW ON_GREEN"
HOSTCOLOR="BOLD RED ON_BLUE"

DEBIAN NEWBIE TIP #41 from Colin Watson <[EMAIL PROTECTED]>
:
Do you need to MASSAGE A BUNCH OF FILE NAMES? There's more
than one way to skin a cat -- here are some examples of
canonicalizing file names to lower-case:
mmv \* \#l1
rename 'tr/A-Z/a-z/' *
zsh -c 'for x in *; do mv "$x" "${x:l}"; done'
(The "rename" command is a standard perl script, by the way.)
