使用SHELL脚本进行检查服务开启情况

#!/bin/bash#需要首先安装 yum install nmap -y#检查指定端口是否开启function checkPortStatus(){        status=`nmap -sS 127.0.0.1 -p $1 | grep open | awk '{print $2}'`        if [ "$status" != "open" ];        then                return 0;        else                return 1;        fi}checkPortStatus 80echo $?checkPortStatus 81echo $?
