cp .env.example .env
# Edit .env with your server details

🚀 Quick Start

1. Configure SSH Connection

Edit .env file:

SERV02_HOST=192.168.68.64
SERV02_PORT=22
SERV02_USERNAME=your_username
SERV02_PASSWORD=your_password
# Or use SSH key
SERV02_PRIVATE_KEY_PATH=/path/to/key

2. Test Connection

# Basic SSH connection test
npm start

# Scan remote directory
npm run scan /home/brian/Projects

# List files via SFTP
npm run sftp list /home/brian/Projects

📖 Usage

Core SSH Connection

# Connect and execute commands
npm start
