title: Nmap greping and awking the results
body: <p>i have nmap and am able to do dns-recursion checks on a local pc. the output is </p>
  
  <p>nmap -sU -p 53 --script=dns-recursion 198.162.3.5</p>
  
  <p>PORT   STATE  SERVICE REASON</p>
  
  <p>53/udp  open  domain  udp-response
  |_dns-recursion: Recursion appears to be enabled</p>
  
  <p>Now my question is if i were to do a scan on all my computers how can i grep and awk in real time ( i donot want to awk and grep the output file) such that only the ip of servers that do recursion are printed. I have the following  command in mind, but itsnot working</p>
  
  <p>nmap -sU -p 53 --script=dns-recursion  | grep "enabled" | awk '{ print $13 }'</p>
