Bash Script Framework

Bash Script Framework

Quick Start

# Create script directory structure
/bash-script-framework init

# Create new script with menu
/bash-script-framework new my-script --menu

# Add to existing scripts directory
/bash-script-framework add utility-script

When to Use

USE when:

• Creating CLI tools for repository
• Building menu-driven automation
• Standardizing script organization
• Cross-platform script development

DON'T USE when:

• Python script is more appropriate
• Simple one-liner needed
• Windows-only environment

For Windows/Git Bash-compatible scripts, see _core/bash/cross-platform-compat.

Prerequisites

• Bash 4.0+
• Unix-like environment (Linux, macOS, WSL)

Overview

Creates organized bash scripts following workspace-hub patterns:

1. Color utilities - Consistent terminal output
2. Menu systems - Multi-level navigation
3. Error handling - Proper exit codes
4. Logging - Timestamped output
5. Cross-platform - Linux/macOS/WSL support

command_exists() {
    command -v "$1" &> /dev/null
}

# Check required commands

### 5. Main Script Template

```bash
#!/bin/bash
# scripts/my-tool - Main entry point
# Description: Tool description here

set -e  # Exit on error
