Nmap Commands for port discovery

Description

Nice and easy Nmap port scans for identifying open ports and outputting into a list of IP addresses.

# One liner for scanning addresses from file and displaying URL addresses in output
nmap -p 80,443,8080,8443,8000 --open -oG - -iL CIDR.txt | grep "/open" | awk '/80\/open/ {print "http://" $2 ":80"} /443\/open/ {print "https://" $2 ":443"} /8080\/open/ {print "http://" $2 ":8080"} /8443\/open/ {print "https://" $2 ":8443"} /8000\/open/ {print "http://" $2 ":8000"}'

# Windows
$results = .\nmap.exe -p 80,443,8080,8443,8000 --open -oG - -iL targets.txt; $results | ForEach-Object { if ($_ -match "Host: (\d+\.\d+\.\d+\.\d+)") { $ip = $matches[1] }; if ($ip) { if ($_ -match "80/open") { "http://{0}:80" -f $ip }; if ($_ -match "443/open") { "https://{0}:443" -f $ip }; if ($_ -match "8080/open") { "http://{0}:8080" -f $ip }; if ($_ -match "8443/open") { "https://{0}:8443" -f $ip }; if ($_ -match "8000/open") { "http://{0}:8000" -f $ip } } }

Similar as above but for Windows, using PowerShell and reading from Targets.txt and outputting to $HOME.
