Editing Nmap

= Nmap =

'''Nmap''' (Network Mapper) is an open‑source utility for network discovery, security auditing, and host fingerprinting.  
It is one of the most widely used tools in active reconnaissance, offering port scanning, OS detection, service versioning, and a powerful scripting interface (Nmap Scripting Engine – NSE).

== <span id="options"></span>Common Options ==

=== Scan Types ===
{| class="wikitable"
! Option !! Description
|-
| [[#ex-sS|<code>-sS</code>]] || TCP SYN scan (stealth mode)
|-
| [[#ex-sT|<code>-sT</code>]] || TCP connect scan (full handshake)
|-
| [[#ex-sU|<code>-sU</code>]] || Scan UDP ports
|-
| [[#ex-sP|<code>-sP</code>]] || Ping scan to discover live hosts (alias for <code>-sn</code>)
|-
| [[#ex-sL|<code>-sL</code>]] || List targets without scanning
|}

=== Host Discovery & Targeting ===
{| class="wikitable"
! Option !! Description
|-
| [[#ex-Pn|<code>-Pn</code>]] || Treat all hosts as online (skip ping)
|-
| [[#ex-p|<code>-p&nbsp;[PORT]</code>]] || Specify port(s) to scan
|-
| [[#ex-iL|<code>-iL&nbsp;[FILE]</code>]] || Input list of hosts from file
|-
| <code>-6</code> || Use IPv6 addresses
|}

=== Detection & Enumeration ===
{| class="wikitable"
! Option !! Description
|-
| [[#ex-sV|<code>-sV</code>]] || Detect service versions
|-
| [[#ex-O|<code>-O</code>]] || Enable OS detection
|-
| [[#ex-A|<code>-A</code>]] || Aggressive scan: OS detection, version, script scan, traceroute
|-
| [[#ex-script|<code>--script&nbsp;[NAME]</code>]] || Run specific NSE script(s)
|}

=== Performance & Output ===
{| class="wikitable"
! Option !! Description
|-
| [[#ex-T|<code>-T[0‒5]</code>]] || Timing template (T0 = slow, T5 = fast)
|-
| [[#ex-d|<code>-d</code>]] || Enable debugging output
|-
