# Simple Shell
## Overview
This project implements a simple Unix-like shell in C. The shell supports basic command execution, piping, input/output redirection, and handling of internal commands like `cd` and `exit`. This shell is designed to demonstrate fundamental concepts in operating systems and process management.
## Features
- **Command Execution**: Execute commands entered by the user.
- **Piping**: Use the output of one command as the input to another.
- **Input/Output Redirection**: Redirect input from a file and output to a file.
- **Internal Commands**: Built-in commands like `cd` (change directory) and `exit` (terminate the shell).
## Installation
### On Windows
1. **Install MinGW:**
- Download and install MinGW from [MinGW SourceForge](https://sourceforge.net/projects/mingw/).
- During installation, select the `mingw32-gcc-g++` package.
- Add the MinGW `bin` directory to your system's PATH environment variable.
2. **Compile the Shell:**
- Open Command Prompt (`cmd`).
- Navigate to the directory containing `shell.c`:
```bash
cd C:\Users\Admin\Desktop\my_shell
```
- Compile the program:
```bash
gcc shell.c -o shell.exe
```
3. **Run the Shell:**
- Execute the compiled shell:
```bash
shell.exe
```
### On Linux or Windows Subsystem for Linux (WSL)
1. **Install WSL:**
- Open PowerShell as Administrator and run:
```bash
wsl --install
```
- Install a Linux distribution from the Microsoft Store (e.g., Ubuntu).
2. **Install GCC:**
- Open the WSL terminal.
- Install GCC:
```bash
sudo apt update
sudo apt install gcc
```
3. **Compile the Shell:**
- Navigate to the directory containing `shell.c`:
```bash
cd /mnt/c/Users/Admin/Desktop/my_shell
```
- Compile the program:
```bash
gcc shell.c -o shell
```
4. **Run the Shell:**
- Execute the compiled shell:
```bash
./shell
```
## Usage
Once you have compiled and run the shell, you can use it by typing commands at the prompt. Here are some examples:
- **Execute a command**:
```bash
ls -l
```
- **Use piping**:
```bash
ls -l | grep ".c"
```
- **Redirect output to a file**:
```bash
echo "Hello, World!" > output.txt
```
- **Redirect input from a file**:
```bash
sort < input.txt
```
