写法1#!/bin/bashfunctionecho_color(){if[$1=="green"];然后echo-e"\033[32;40m$2\033[0m"elif[$1=="red"];那么echo-e"\033[31;40m$2\033[0m"fi}echo_colorgreen"我是绿的"echo_colorred"我是红的"也可以写在前面除了写函数，还可以定义一个函数#!/bin/bashecho_color(){case$1ingreen)echo-e"\033[32;40m$2\033[0m";;red)echo-e"\033[31;40m$2\033[0m";;*)echo"Example:echo_colorredstring"esac}echo_colorgreen"我是绿色的"更多建站和源码交易请见GoodMai好购网
