找到結果後逐漸顯示nmap結果

要獲得nmap結果，必須等待掃描結束。

如何在nmap執行時強制逐步顯示新找到的主機和打開的埠？

添加此命令行開關：

-v (Increase verbosity level) .

   Increases the verbosity level, causing Nmap to print more information about 
   the scan in progress. Open ports are shown as they are found and completion 
   time estimates are provided when Nmap thinks a scan will take more than a few 
   minutes. Use it twice or more for even greater verbosity: -vv, or give a 
   verbosity level directly, for example -v3..
