    Nmap 7.80 ( 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 <inputfilename>: Input from list of hosts/networks
      -iR <num hosts>: Choose random targets
      --exclude <host1[,host2][,host3],...>: Exclude hosts/networks
      --excludefile <exclude_file>: 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 <flags>: Customize TCP scan flags
      -sI <zombie host[:probeport]>: Idle scan
      -sY/sZ: SCTP INIT/COOKIE-ECHO scans
      -sO: IP protocol scan
      -b <FTP relay host>: FTP bounce scan
    PORT SPECIFICATION AND SCAN ORDER:
      -p <port ranges>: Only scan specified ports
        Ex: -p22; -p1-65535; -p U:53,111,137,T:21-25,80,139,8080,S:9
      --exclude-ports <port ranges>: Exclude the specified ports from scanning
      -F: Fast mode - Scan fewer ports than the default scan
      -r: Scan ports consecutively - don't randomize
      --top-ports <number>: Scan <number> most common ports
      --port-ratio <ratio>: Scan ports more common than <ratio>
    SERVICE/VERSION DETECTION:
      -sV: Probe open ports to determine service/version info
      --version-intensity <level>: 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=<Lua scripts>: <Lua scripts> 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=<Lua scripts>: Show help about scripts.
               <Lua 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 <time> 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 <size>: Parallel host scan group sizes
      --min-parallelism/max-parallelism <numprobes>: Probe parallelization
      --min-rtt-timeout/max-rtt-timeout/initial-rtt-timeout <time>: Specifies
          probe round trip time.
      --max-retries <tries>: Caps number of port scan probe retransmissions.
      --host-timeout <time>: Give up on target after this long
      --scan-delay/--max-scan-delay <time>: Adjust delay between probes
      --min-rate <number>: Send packets no slower than <number> per second
      --max-rate <number>: Send packets no faster than <number> per second
    FIREWALL/IDS EVASION AND SPOOFING:
      -f; --mtu <val>: fragment packets (optionally w/given MTU)
      -D <decoy1,decoy2[,ME],...>: Cloak a scan with decoys
      -S <IP_Address>: Spoof source address
      -e <iface>: Use specified interface
