for(( i=0;i<${#port_array[@]};i++)) do
 
    time=$(date "+%Y-%m-%d %H:%M:%S") 
    port=${port_array[i]};
    service_name=${service_array[i]};
    port_status=`netstat -nlt|grep ${port_array[i]}|wc -l`
  
    if [ $port_status -lt 1 ]
    then
        echo -e "\033[31m[FAIL] $time $service_name:$port\033[0m"
    else
        echo -e "\033[32m[INFO] $time $service_name:$port\033[0m"
