NMAP allows you to map your network from the command line and output the results into a text format.

Make sure to run NMAP as root, or with sudo command. Root provides MAC Address and Vendor Information.

-A — Aggressive scan tries to find OS
-F — Scans only most popular 100 ports
-v — verbose output for command line
-oN — Outputs to Human Readable Text File
-oX — Outputs to XML file for Parsing

Examples:
sudo nmap -v 192.168.1.1

sudo nmap 192.168.1.0/24 -oN /home/username/nmap.txt

sudo nmap -A -F 192.168.1.0/24 -oX /home/username/nmap.xml
