一、echo命令(带参数-e)
cat color.sh
#!/bin/bash
echo -e "\033[30m black \033[0m"
echo -e "\033[31m red \033[0m"
echo -e "\033[32m green \033[0m"
echo -e "\033[33m yellow \033[0m"
echo -e "\033[34m blue \033[0m"
echo -e "\033[35m purple \033[0m"
echo -e "\033[36m cyan \033[0m"
echo -e "\033[37m white \033[0m"
% x( m# j" k# _$ M6 M二、printf命令
cat color2.sh
#!/bin/bash
printf "\033[30m black \033[0m\n"
printf "\033[31m red \033[0m\n"
printf "\033[32m green \033[0m\n"
printf "\033[33m yellow \033[0m\n"
printf "\033[34m blue \033[0m\n"
printf "\033[35m purple \033[0m\n"
printf "\033[36m cyan \033[0m\n"
printf "\033[37m white \033[0m\n"
6 A$ s( ? u- B# |( a9 H/ p5 h! c三、使用变量
cat color3.sh
#!/bin/bash
blackcolor='\E[1;30m'
redcolor='\E[1;31m'
greencolor='\E[1;32m'
yellowcolor='\E[1;33m'
bluecolor='\E[1;34m'
purplecolor='\E[1;35m'
cyancolor='\E[1;36m'
whitecolor='\E[1;37m'
echo -e "${blackcolor}black"
echo -e "${redcolor}red"
echo -e "${greencolor}green"
echo -e "${yellowcolor}yellow"
echo -e "${bluecolor}blue"
