Save Nmap’s output

You can save Nmap’s output to a file. Three different formats are available:

  • XML output – can be converted to HTML and or imported into databases. The -oX filename flag is used to specify the output in this form:
root@kali:~# nmap -p21,22,80,135 -oX results.xml
root@kali:~# cat results.txt
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE nmaprun>
<?xml-stylesheet href="file:///usr/bin/../share/nmap/nmap.xsl" type="text/xsl"?>

  • grepable output – designed to be used by the Linux tool grep. It is invoked using the -oG flag:
root@kali:~# nmap -p21,22,80,135 -oG results.grep
root@kali:~# cat results.grep
# Nmap 7.01 scan initiated Sat Mar 5 19:12:44 2016 as: nmap -p21,22,80,135 -oG results.grep
Host: () Status: Up
Host: () Ports: 21/open/tcp//ftp///, 22/closed/tcp//ssh///, 80/open/tcp//http///, 135/open/tcp//msrpc///
# Nmap done at Sat Mar 5 19:12:45 2016 -- 1 IP address (1 host up) scanned in 1.05 seconds
  • human readable output – produces a normal output format. It is invoked with the -oN flag:
root@kali:~# nmap -p21,22,80,135 -oN results.txt
root@kali:~# cat results.txt
# Nmap 7.01 scan initiated Sat Mar 5 19:17:10 2016 as: nmap -p21,22,80,135 -oN results.txt
Nmap scan report for

21/tcp open ftp
22/tcp closed ssh
80/tcp open http
135/tcp open msrpc
# Nmap done at Sat Mar 5 19:17:11 2016 -- 1 IP address (1 host up) scanned in 1.04 seconds

To output all three log files, use the -oA flag.
