CodeSnippets: ANSI terminal color chart

ansi_terminal_color.sh

#!/bin/bash
#
#   This file echoes a bunch of color codes to the
#   terminal to demonstrate what's available.  Each
#   line is the color code of one forground color,
#   out of 17 (default + 16 escapes), followed by a
#   test use of that color on all nine background
#   colors (default + 8 escapes).
