Linux 检查端口gps命令

由于是游戏业务，环境主要是Nginx+Tomcat+Java Program

gps脚本环境以及效果图如下：

#!/bin/bash

function Printf (){
    if [ $1 == 1 ];then
        printf '%-50s\n' "+-----------------+------------------+-----------------+"
        shift 1
    fi
    printf '%1s %-10s %1s %10s  %1s %10s %1s\n' "|"  "$1"  "|" "$2" "|" "$3" "|"
    printf '%-50s\n' "+-----------------+------------------+-----------------+"
}

    else
        Status=$(echo -e "\e[31mError\e[0m")
