This options summary is printed when Nmap is run with no arguments, and the latest version is always available athttps://svn.nmap.org/nmap/docs/nmap.usage.txt. It helps people remember the most common options, but is no substitute for the in-depth documentation in the rest of this manual. Some obscure options aren't even included here.

Nmap 7.93SVN ( https://nmap.org ) Usage: nmap [Scan Type(s)] [Options] {target specification} TARGET SPECIFICATION: Can pass hostnames, IP addresses, networks, etc. Ex: scanme.nmap.org, microsoft.com/24, 192.168.0.1; 10.0.0-255.1-254 -iL : Input from list of hosts/networks -iR : Choose random targets --exclude <host1[,host2][,host3],...>: Exclude hosts/networks --excludefile : Exclude list from file HOST DISCOVERY: -sL: List Scan - simply list targets to scan -sn: Ping Scan - disable port scan -Pn: Treat all hosts as online -- skip host discovery -PS/PA/PU/PY[portlist]: TCP SYN/ACK, UDP or SCTP discovery to given ports -PE/PP/PM: ICMP echo, timestamp, and netmask request discovery probes -PO[protocol list]: IP Protocol Ping -n/-R: Never do DNS resolution/Always resolve [default: sometimes] --dns-servers <serv1[,serv2],...>: Specify custom DNS servers --system-dns: Use OS's DNS resolver --traceroute: Trace hop path to each host SCAN TECHNIQUES: -sS/sT/sA/sW/sM: TCP SYN/Connect()/ACK/Window/Maimon scans -sU: UDP Scan -sN/sF/sX: TCP Null, FIN, and Xmas scans --scanflags : Customize TCP scan flags -sI <zombie host[:probeport]>: Idle scan -sY/sZ: SCTP INIT/COOKIE-ECHO scans -sO: IP protocol scan -b : FTP bounce scan PORT SPECIFICATION AND SCAN ORDER: -p : Only scan specified ports Ex: -p22; -p1-65535; -p U:53,111,137,T:21-25,80,139,8080,S:9 --exclude-ports : Exclude the specified ports from scanning -F: Fast mode - Scan fewer ports than the default scan -r: Scan ports sequentially - don't randomize --top-ports : Scan most common ports --port-ratio : Scan ports more common than SERVICE/VERSION DETECTION: -sV: Probe open ports to determine service/version info --version-intensity : Set from 0 (light) to 9 (try all probes) --version-light: Limit to most likely probes (intensity 2) --version-all: Try every single probe (intensity 9) --version-trace: Show detailed version scan activity (for debugging) SCRIPT SCAN: -sC: equivalent to --script=default --script=: is a comma separated list of directories, script-files or script-categories --script-args=<n1=v1,[n2=v2,...]>: provide arguments to scripts --script-args-file=filename: provide NSE script args in a file --script-trace: Show all data sent and received --script-updatedb: Update the script database. --script-help=: Show help about scripts. is a comma-separated list of script-files or script-categories. OS DETECTION: -O: Enable OS detection --osscan-limit: Limit OS detection to promising targets --osscan-guess: Guess OS more aggressively TIMING AND PERFORMANCE: Options which take are in seconds, or append 'ms' (milliseconds), 's' (seconds), 'm' (minutes), or 'h' (hours) to the value (e.g. 30m). -T<0-5>: Set timing template (higher is faster) --min-hostgroup/max-hostgroup : Parallel host scan group sizes --min-parallelism/max-parallelism : Probe parallelization --min-rtt-timeout/max-rtt-timeout/initial-rtt-timeout : Specifies probe round trip time. --max-retries : Caps number of port scan probe retransmissions. --host-timeout : Give up on target after this long --scan-delay/--max-scan-delay : Adjust delay between probes --min-rate : Send packets no slower than per second --max-rate : Send packets no faster than per second FIREWALL/IDS EVASION AND SPOOFING: -f; --mtu : fragment packets (optionally w/given MTU) -D <decoy1,decoy2[,ME],...>: Cloak a scan with decoys -S : Spoof source address -e : Use specified interface -g/--source-port : Use given port number --proxies <url1,[url2],...>: Relay connections through HTTP/SOCKS4 proxies --data : Append a custom payload to sent packets --data-string : Append a custom ASCII string to sent packets --data-length : Append random data to sent packets --ip-options : Send packets with specified ip options --ttl : Set IP time-to-live field --spoof-mac <mac address/prefix/vendor name>: Spoof your MAC address --badsum: Send packets with a bogus TCP/UDP/SCTP checksum OUTPUT: -oN/-oX/-oS/-oG : Output scan in normal, XML, s|<rIpt kIddi3, and Grepable format, respectively, to the given filename. -oA : Output in the three major formats at once -v: Increase verbosity level (use -vv or more for greater effect) -d: Increase debugging level (use -dd or more for greater effect) --reason: Display the reason a port is in a particular state --open: Only show open (or possibly open) ports --packet-trace: Show all packets sent and received --iflist: Print host interfaces and routes (for debugging) --append-output: Append to rather than clobber specified output files --resume : Resume an aborted scan --noninteractive: Disable runtime interactions via keyboard --stylesheet <path/URL>: XSL stylesheet to transform XML output to HTML --webxml: Reference stylesheet from Nmap.Org for more portable XML --no-stylesheet: Prevent associating of XSL stylesheet w/XML output MISC: -6: Enable IPv6 scanning -A: Enable OS detection, version detection, script scanning, and traceroute --datadir : Specify custom Nmap data file location --send-eth/--send-ip: Send using raw ethernet frames or IP packets --privileged: Assume that the user is fully privileged --unprivileged: Assume the user lacks raw socket privileges -V: Print version number -h: Print this help summary page.
