Linux下用nmap扫描端口的shell脚本

Question

如扫描192.168.1.100-200之间所有开启80或22或8808端口的服务器，并把结果输出到test.log文件中。要求日志文件格式包括序列号1、2、3···，服务器IP，开启的端口号，扫描时间。求大神用shell脚本帮忙实现一下，多谢
可以是只扫描一个端口的脚本，比如只扫描80

这问题我是没太看明白 ，按我理解的：

#!/bin/bash
port="80/tcp"

for i in seq 1 1
do
Time=nmap 192.168.1.$i | grep Starting | awk '{print $8,$9}'
echo "1：Time:$Time" >> test.log
Ip=nmap 192.168.1.$i | grep report |awk '{print $5}'
echo "2: IP:$Ip" >> test.log
Rtime=nmap 192.168.1.$i | grep seconds | awk '{print $11}'
echo "3: Rtime:$Rtime"
nmap 192.168.1.$i | grep $port
if [ $? = 0 ]
then
echo "3: $port " >> test.log
echo " "
echo "============================================== "
else

            echo "'80' is not exist"  >>test.log
            echo " "
            echo "============================================== "
    fi 

    done
