Users who have been using Linux for awhile often learn that creating a basic script is a good way to run multiple, often-repeated commands. Adding a little color to scripts can additionally provide nice feedback. This can be done in a fairly straight-forward way by using the tput command.
A common way of doing this is to define the colors that tnput can produce by putting them at the beginning of the bash script:
#!/bin/bash
# tputcolors
red="\033[00;31m"
RED="\033[01;31m"
green="\033[00;32m"
GREEN="\033[01;32m"
brown="\033[00;33m"
YELLOW="\033[01;33m"
blue="\033[00;34m"
BLUE="\033[01;34m"
purple="\033[00;35m"
PURPLE="\033[01;35m"
cyan="\033[00;36m"
CYAN="\033[01;36m"
white="\033[00;37m"
WHITE="\033[01;37m"
NC="\033[00m"
