#!/bin/bash

port_array=(`netstat -ntpl|egrep -i "$1"|awk ‘print $4‘|awk -F‘:‘ ‘if ($NF~/^[0-9]*$/) print $NF‘|sort|uniq`)
length=$#port_array[@]

printf "\n"
printf ‘\t‘"\"data\":["
for ((i=0; i<$length; i++))
do
    printf ‘\n\t\t‘
    printf "\"#TCP_PORT\":\"$port_array[$i]\""
    if [ $i -lt $[$length - 1] ]; then
        printf ‘,‘
    fi
done

printf "\n\t]\n"
printf "\n"

输出
