CRITICAL SECURITY WARNING - FORTRESS PROTECTION

Maximum Security - FORTRESS SECURITY

• Always use latest version: Older versions (< 3.0.0) have security vulnerabilities
• Avoid legacy versions: Versions 2.1.x-2.5.3 lack latest Smart File Analysis
• Use @latest flag: npx @chahuadev/emoji-cleaner@latest for maximum safety
• VERSION 2.5.3+ RECOMMENDED: Latest version includes enhanced Smart File Analysis system

Anti-Hack Protection System - FORTRESS SHIELD

Tool has comprehensive protection against all attack vectors:

Command Injection Protection

npm install -g @chahuadev/emoji-cleaner

Usage

Basic Usage

# Clean current directory with backup (Recommended)
npx @chahuadev/emoji-cleaner@latest . --backup

# Preview changes first (Safe!)
npx @chahuadev/emoji-cleaner@latest . --dry-run --verbose

# Clean specific file types
npx @chahuadev/emoji-cleaner@latest src/ --extensions js,ts,jsx,tsx

Advanced Options

# JSON output for CI/CD
npx @chahuadev/emoji-cleaner@latest . --output json > results.json

# Exclude specific patterns
npx @chahuadev/emoji-cleaner@latest . --exclude "*.min.js,dist/**"

# Verbose logging
npx @chahuadev/emoji-cleaner@latest . --backup --verbose

Security Features

Multi-Layer Protection

• Command Injection Protection - Blocks dangerous functions and shell commands
• Path Traversal Protection - Validates file paths and prevents directory traversal
• System File Protection - Protects critical system files from modification
• Input Sanitization - Comprehensive input validation and sanitization

Security Best Practices

• Always use version 2.5.3+ for latest security patches
