一、echo命令(帶參數-e)cat color.sh#!/bin/bashecho -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"執行結果:bash color.sh black red green yellow blue purple cyan white 二、printf命令cat color2.sh#!/bin/bashprintf "\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"執行結果:bash color2.sh black red green yellow blue purple cyan white三、使用變數cat color3.sh#!/bin/bashblackcolor=‘\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 "${bluecolor}blue"echo -e "${purplecolor}purple"echo -e "${cyancolor}cyan"echo -e "${whitecolor}white"執行結果:bash color3.shblackredgreenyellowbluepurplecyanwhite四、系統函數cat color4.sh#!/bin/bashblackcolor="echo -en \\033[1;30m"redcolor="echo -en \\033[1;31m"greencolor="echo -en \\033[1;32m"yellowcolor="echo -en \\033[1;33m"bluecolor="echo -en \\033[1;34m"purplecolor="echo -en \\033[1;35m"cyancolor="echo -en \\033[1;36m"whitecolor="echo -en \\033[1;37m"echo black && ${blackcolor}echo red && ${redcolor}echo green && ${greencolor}echo yellow && ${yellowcolor}echo blue && ${bluecolor}echo purple && ${purplecolor}echo cyan && ${cyancolor}echo white && ${whitecolor}執行結果:bash color4.shblackredgreenyellowbluepurplecyanwhite
