2. Java uses color output

• java code

3. The shell uses colored output

• sh script

START='\e[';
END=m;

#使用1个样式、颜色
echo -e "${START}31${END}我是红色前景"
echo -e "你猜我啥颜色？"
echo -e "${START}91${END}我是亮红色前景${START}0${END}"
echo -e "你猜我啥颜色？"
echo -e "${START}41${END}我是红色背景${START}0${END}"
echo -e "${START}3${END}我是斜体${START}0${END}"

#同时使用多个样式、颜色
echo -e "${START}34;103${END}我是蓝色前景、亮黄色背景${START}0${END}"
echo -e "${START}34${END}${START}103${END}我是蓝色前景、亮黄色背景${START}0${END}"
