2、bash代码

#main
echo -e "example ... [\e[1;30m black \e[0m|\e[1;31m red \e[0m|\e[1;32m green \e[0m|\e[1;33m yellow \e[0m|\e[1;34m blue \e[0m|\e[1;35m magenta \e[0m|\e[1;36m cyan \e[0m|\e[1;37m white \e[0m]"
echo -en "using [\e[1;40m echo_black \"hello\"\e[0m ] to output black text: "
echo_black "hello"
echo -en "using [\e[1;41m echo_red \"hello\" \e[0m] to output red text: "
echo_red "hello"
echo -en "using [\e[1;42m echo_green \"hello\" \e[0m] to output green text: "

echo_cyan "hello"
echo -en "using [\e[1;47m echo_white \"hello\" \e[0m] to output white text: "
echo_white "hello"
echo -en "using [\e[30;47m echo_black -b white \"hello,world!\" \e[0m] to output black text with white background: "
echo_black -b white "hello, world!" 

3、其他脚本中使用示例

example.sh

#!/bin/bash

#导入color.sh脚本,即可调用里面的函数(若exmaple.sh与color.sh不在同一目录，下面的导入记得使用color.sh的绝对路径)
. color.sh

echo_red "red message"
echo_blue -b white "blue message, white background"
