## 📦 Requirements

To build MyCMD you need:

- [Java JDK 17+](https://adoptium.net/)  
- [Apache Maven](https://maven.apache.org/)  
- [Launch4j](https://launch4j.sourceforge.net/) (for `.exe` wrapping)  
- [Inno Setup](https://jrsoftware.org/isinfo.php) (for Windows installer)  

*(Linux users can use `jpackage` instead of Launch4j/Inno Setup.)*

## 🛠️ Build Instructions
Building MyCMD is simple and automated for both Windows 🪟 and Linux 🐧 platforms

### 🔹 Windows
```bash
scripts\build-windows.bat

📦 This script will automatically:

1.🧩 Build the JAR using Apache Maven

2.⚙️ Wrap it into an .exe using Launch4j

3.🪄 Generate a setup.exe installer via Inno Setup

Final Output

dist/
 ┣ bin/MyCMD.exe
 ┣ lib/dependencies.jar
 ┗ setup.exe

Linux

chmod +x scripts/build-linux.sh
./scripts/build-linux.sh

This will build a .deb or .rpm package using jpackage.

🖥️ Usage

After installation, run:

MyCMD

You can now use commands like:

> dir
> cd ..
> mkdir test
> echo Hello World!
> type file.txt
> del file.txt
> help
> exit

🧩 Extending MyCMD

Note

There are many commands left like ls and Ping Command
