Bash Ansi Color Helper Script

bash_ansi_color.sh

#!/bin/bash
# A helper script to define ANSI code and provide 'echo' and 'printf' functions to printf/echo ansi strings

# Usage:
#     source bash_ansi_color.sh
#     printf_ansi "This is BOLD AND RED\n" $ANSI_TEXT_BOLD_RED
#     echo_ansi "Echo applies newlines!" $ANSI_TEXT_UNDERLINE_PURPLE $ANSI_BACKGROUND_YELLOW
