+## Simple Nmap Scripts
+***
+
+Hola! :wave: Let's begin writing a simple Nmap script. Nmap is like a detective tool for computer networks. It helps you discover which devices are connected to a network, what services they're running, and how secure they are.
+
+## Why Nmap🤔?
+
+Nmap is used for network exploration and security auditing. It helps users discover devices on a network, identify open ports, and analyze network security.

+
+## Scripts
+
+Let's proceed 🚀 to explain how the script works. This script is based on Nmap's TCP Connect Scan. I'll also be creating scripts for different types of scans in the future.
+
+- First of all, I create a script by opening a text editor and naming the file with the extension ".sh" in this Nmap script. I also give it permission so that I can run it. Additionally, I was able to run it, but in this case, I'm not specifying any IP addresses or port numbers. Now, let me explain how the script works 😄.

+
+## Explanation of the Scripts:
+***

+
+So, I started the script with the shebang 👉( #! /bin/bash) so that the interpreter will understand it is a Bash script. 
+In the second and third lines, I specify a comment, i.e., #, which doesn't execute. The comment serves as a guide; it doesn't execute any commands. It's simply a way for anyone editing the script to understand how it works and make corrections if necessary.
+
+## command use:
+
+- The echo command displays text on the terminal,to printing a message. For instance, echo "Hello, world!" prints "Hello, world!" to the screen.
+- The sleep command temporarily stops script execution for a set duration. For instance, sleep 5 pauses the script for 5 seconds before continuing to the next instruction.
+- The read command is used to take input from the user while the script is running. It prompts the user to enter some text, which is then stored in a variable for the script to use.
+- The Nmap command, in this case, is used specifically for conducting a TCP connect scan, focusing on a specific port and IP address. in the i use nmap -sT ip addr port
+So in this : The command "nmap -sT" instructs Nmap to perform a TCP connect scan. In a TCP connect scan, Nmap attempts to establish a full TCP connection with the target ports to determine whether they are open, closed, or filtered by a firewall. This method is more reliable but also more detectable than other scan types.
