Colored output in bash script

Implementation varies between platforms, see below.

Usage

cecho "Hello world" yellow

White terminal?

This script assumes your terminal has a black background, to use with white terminals replace ;40m with ;47m for each color. (There are more colors, try them out!)

OSX

cecho() {
    black='\033[30;40m'
    red='\033[31;40m'
    green='\033[32;40m'
    yellow='\033[33;40m'
    blue='\033[34;40m'
    magenta='\033[35;40m'
    cyan='\033[36;40m'
    white='\033[37;40m'

    echo -e ${!2}$1
    tput sgr0
    return
