Cheat Sheet of Nmap or Zenmap

All of you guys are aware of Nmap (Network Mapping). It is a very famous port scanner available for free.
It is not just only a port scanner, it also do various jobs like banner grabbing, OS fingerprinting, run scripts etc.
So I'm gonna show you some important commands of Nmap.





Requisites: Nmap

Step 1: Open up the console and type:  
nmap
                                           
It will give you the whole commands of nmap.
But we are here to understanding the commands so we should go ahead.

Here is the cheatsheet of NMAP.
