Certainly! Here is a simplified `README.md` that provides clear instructions for setting up the project, cloning the repository, and updating the `zsh` configuration for the alias.
### README.md
```markdown
# Image Converter
This project provides a script to convert WEBP and HEIC images to PNG and JPG formats using ImageMagick.
## Setup Instructions
### Prerequisites
Make sure you have ImageMagick installed. You can check if it's installed by running:
```bash
convert -version
```
If not installed, you can install it using:
- **macOS**:
```bash
brew install imagemagick
```
- **Ubuntu**:
```bash
sudo apt-get update
sudo apt-get install imagemagick
```
- **Windows**:
Download and install from the [ImageMagick website](https://imagemagick.org/script/download.php).
### Project Setup
1. **Clone the repository**:
```bash
git clone https://github.com/yourusername/image-converter.git
cd image-converter
```
2. **Make the script executable**:
```bash
chmod +x convert_images.sh
```
3. **Add an alias to your shell configuration file**:
```bash
echo "alias convert='~/path_to_your_script_directory/convert_images.sh'" >> ~/.zshrc
source ~/.zshrc
```
Replace `~/path_to_your_script_directory` with the actual path where you cloned the repository.
## Usage
To convert a WEBP or HEIC file to PNG and JPG, use the following command:
```bash
convert filename.webp
```
or
```bash
convert filename.heic
```
The converted files will be saved in `~/Pictures/Converted`.
```
### Complete Project Code
1. **Project Directory Structure**:
```
image-converter/
├── convert_images.sh
├── README.md
└── .gitignore
```
2. **convert_images.sh**:
```bash
#!/bin/bash
# Check if the magick command is available
if ! command -v magick &> /dev/null; then
echo "ImageMagick is not installed or not in your PATH."
exit 1
fi
# Get the input file from the command line argument
input_file=$1
# Check if input file is provided
if [ -z "$input_file" ]; then
echo "Error: No input file specified. Usage: convert file1.webp or convert file1.heic"
exit 1
fi
# Extract the base name and extension of the input file
base_name=$(basename "$input_file" | cut -d. -f1)
extension=$(basename "$input_file" | cut -d. -f2)
# Define the output directory
output_dir="$HOME/Pictures/Converted"
# Check if the output directory exists, create if it does not
if [ ! -d "$output_dir" ]; then
mkdir -p "$output_dir"
fi
# Function to convert images
convert_images() {
local input_file=$1
local base_name=$2
local output_dir=$3
# Convert to PNG
magick "$input_file" "$output_dir/${base_name}.png"
echo "Converted $input_file to $output_dir/${base_name}.png"
# Convert to JPG
magick "$input_file" "$output_dir/${base_name}.jpg"
echo "Converted $input_file to $output_dir/${base_name}.jpg"
}
# Check the file extension and convert if it is .webp or .heic
if [ "$extension" = "webp" ] || [ "$extension" = "heic" ]; then
convert_images "$input_file" "$base_name" "$output_dir"
else
echo "Error: The file must be either .webp or .heic."
exit 1
fi
```
3. **.gitignore**:
```gitignore
# Ignore log files and temp files
*.log
*.tmp
```

cd image-converter
git init
git add .
git commit -m "Initial commit with image conversion script"
```
2. **Push to GitHub**:
- Create a new repository on GitHub.
- Add the remote repository and push your code:
```bash
git remote add origin https://github.com/yourusername/image-converter.git
git branch -M main
