+### Ping Scanning 🏓
+
+```bash
+nmap -sn 192.168.10.1
+nmap -sP 192.168.10.2
+```
+
+### ARP Scanning 🌐
+
+```bash
+nmap -sP -PR 192.168.10.1
+```
+> **Tip**: Press the spacebar to show the current progression of the scan.
+
+### SYN Scanning 🚀
+
+```bash
+nmap -sS 192.168.10.1
+```
+
+### UDP Scanning 🚁
+
+```bash
+nmap -sU 192.168.10.1
+```
+
+### Useful Nmap Switches 🎛️
+
+- `-h` help
+- `-v` verbose
+- `-vv` very verbose
+- `-n` no DNS reverse lookup
+- `-T` sets the speed of the scan (`-T5` being the fastest, `-T0` the slowest)
+- `-p 80` specific port
+- `-p 1-10` range of ports
+- `-p-` all ports
+- `-o` to output a file
+
+### Identifying OS and Applications 🖥️
+
+- `-sV` enable version detection
+- `-O` enables OS detection
+- `-A` enables OS detection, Version detection, Script scanning, and traceroute
+- `--osscan-guess` Aggressive OS guessing
+
+### Nmap Scripts 📜
+
+**Syntax**: `nmap —script scriptname targetIP`
+
+```bash
+nmap —script http-headers 192.168.10.1
+nmap —script smtp-commands 192.168.10.1
+```

+
+### Batch Scripts 📚
+
+**Steps**:
+
+1. Download `neovim` or your favorite text editor.
+2. Create a script file: `nvim nmapScan.sh`
+3. Paste the following content:
+
+```bash
+#!/bin/bash
+
+nmap -sT -p 1-10000 -v -v -T5 -sV -O --osscan-guess --script=banner -oN 192.168.10.1TCP.txt 192.168.10.1
+nmap -sU -p 1-500 -v -v --scan-delay 1s -sV --script=banner -oN 192.168.10.1UDP.txt 192.168.10.1
+```
+
+4. Save and exit.
+5. Make the script executable:
+
+```bash
+sudo chmod +x nmapScan.sh
+```
+
+6. Run the script:
+
+```bash
+sudo ./nmapScan.sh
+```
+```
