Search for Nmap NSE scripts:
$ find /usr/share/nmap/scripts/ -type f | grep smb
Or
$ sudo nmap --script-updatedb
$ cat /usr/share/nmap/scripts/script.db | grep smb
Configure Nmap to run as unprivileged user by setting Linux capabilities:
$ sudo setcap cap_net_raw,cap_net_admin,cap_net_bind_service+eip `which nmap`
$ nmap --privileged ...
Grep only numbers to get a comma-separated list of ports:
$ cat nmap/initial.nmap | egrep -o '^[0-9]{1,5}' | awk -F/ '{ print $1 }' ORS=','; echo
Define which NSE scripts were ran:
$ grep '|_' services/alltcp-versions.nmap | cut -d'_' -f2 | cut -d' ' -f1 | sort -u | grep ':'
Look at HTTP titles:
$ grep -i 'http-title' services/alltcp-versions.nmap

$ ports=`cat masscan/ports | awk -F " " '{print $4}' | awk -F "/" '{print $1}' | sort -n | tr "\n" ',' | sed 's/,$//'`
