MOTD with colors! (also applies to shell profiles)

I'm not sure why I had never looked into this before, but this evening I became obsessed with discovering how to present different colored text in the /etc/motd. A person had suggested creating a shell script (rather than using special editing modes in vi, or something) and I agree that is the simplest way of getting this accomplished quickly.

This most noteworthy portion of this script is the following:

RESET="\033[0m"

that puts the users shell back to the original color. I typically like a green text on black background.

Also - a great reference for the different colors and font-type (underscore, etc...)

I found this example on the web and I wish I could recall where so that I could provide credit to that person.

#!/bin/bash
#define the filename to use as output
motd="/etc/motd"
# Collect useful information about your system
# $USER is automatically defined
HOSTNAME=`uname -n`
KERNEL=`uname -r`
CPU=`uname -p`
ARCH=`uname -m`
# The different colours as variables
W="\033[01;37m" # WHITE
B="\033[01;34m" # BLUE
G="\033[01;32m" # GREEN 
R="\033[01;31m" # RED
X="\033[00;37m" # Not sure...
RESET="\033[0m"
clear > $motd # to clear the screen when showing up
