A Nice Color Scheme Tester Script for Terminal Shell

This is a shell script that outputs your current unix color scheme. This is handy for when you’re trying to come up with your own theme. It comes from http://www.frexx.de/xterm-256-notes/. I’m taking no original credit for this script. I simply want to share it with the readers since I found it very clean and useful. You simply copy the code to a script, use ‘chmod +x colortheme.sh’ as usual, and then run it with ./colorscheme.sh. I’m going to duplicate the script here for redundancy (I want to make sure it’s always there for myself too!):

#!/bin/bash
#
# Description:
#
#    Prints a color table of 8bg * 8fg * 2 states (regular/bold)
