# Shell Script Template

A modern Bash script template with colorized output formatting and utility functions for creating professional command-line tools.

## Features

- 🎨 **Colorized Output**: Pre-defined color schemes and formatting functions
- 📝 **Standardized Messages**: Consistent info, success, warning, and error message formats
- 🔧 **Utility Functions**: Ready-to-use functions for common shell script operations
- 📦 **Modular Design**: Separate library file for easy reuse across projects
- ⚡ **Easy Setup**: Simple sourcing mechanism for immediate use

## Quick Start

1. Clone or download this template
2. Make your script executable:
   ```bash
   chmod +x script.sh
   ```
3. Run the example script:
   ```bash
   ./script.sh
   ```

## Usage

### Basic Template Structure

```bash
#!/bin/bash

LIB="lib"
source $LIB/format.sh

section "Your Script Section"
info "Information message"
ok "Success message" 
warn "Warning message"
error "Error message"
```

### Available Functions

#### Message Types
- `info "message"` - Displays informational messages with cyan `[i]` prefix
- `ok "message"` - Displays success messages with green `[+]` prefix
- `warn "message"` - Displays warning messages with yellow `[!]` prefix
- `error "message"` - Displays error messages with red `[-]` prefix (sent to stderr)

#### Interactive Functions
- `prompt "question"` - Displays a prompt with magenta `[?]` prefix and waits for user input
- `section "title"` - Creates a formatted section header

#### Text Formatting
- `bold "text"` - Displays text in bold formatting

### Color Constants

The following color constants are available for custom formatting:

```bash
RED='\033[0;31m'
GREEN='\033[0;32m'
YELLOW='\033[1;33m'
BLUE='\033[0;34m'
MAGENTA='\033[0;35m'
CYAN='\033[0;36m'
WHITE='\033[1;37m'
BOLD='\033[1m'
UNDERLINE='\033[4m'
RESET='\033[0m'
```

## Example Output

When you run the example script, you'll see:

```
=== Start ===
[i] Running exploit setup...
[+] Everything is ready
[!] This might break your system
[-] Something failed
[?] Continue? [y/N]:
```

## File Structure

```
shell_template/
├── script.sh          # Example script demonstrating usage
├── lib/
│   └── format.sh       # Core formatting library
├── LICENSE             # MIT License
└── README.md          # This file
```

## Customization

### Adding New Message Types

You can extend the library by adding new message types in `lib/format.sh`:

```bash
DEBUG="${BLUE}[D]${RESET}"
debug() { echo -e "${DEBUG} $*"; }
```

### Custom Colors

Define your own color schemes by modifying the color constants or creating new ones:

```bash
PURPLE='\033[0;35m'
CUSTOM_PREFIX="${PURPLE}[*]${RESET}"
custom() { echo -e "${CUSTOM_PREFIX} $*"; }
```

## Best Practices

1. **Always source the library**: Include `source $LIB/format.sh` at the beginning of your scripts
2. **Use appropriate message types**: Choose the right function for the context (info, ok, warn, error)
3. **Structure with sections**: Use `section` to organize your script output
4. **Handle errors properly**: Use `error` for error messages and redirect to stderr
5. **Make scripts executable**: Don't forget `chmod +x` for your scripts
