Usage

Interactive TUI

moonbit              # Launch interactive TUI

The TUI offers two scan modes:

• Quick Scan - Fast scan of safe caches only (~25 categories)
• Deep Scan - Comprehensive scan of all categories including system logs

CLI Commands

# Scanning
moonbit scan                    # Standard scan
moonbit scan --mode quick       # Quick scan (safe caches only)
moonbit scan --mode deep        # Deep scan (all categories)

# Cleaning
moonbit clean                   # Preview what would be deleted (dry-run)
moonbit clean --force           # Actually delete files
moonbit clean --mode quick      # Clean only quick scan categories
moonbit clean --mode deep       # Clean all scanned categories

# Package manager cleanup
moonbit pkg orphans             # Remove orphaned packages
moonbit pkg kernels             # Remove old kernels (Debian/Ubuntu)

# Docker cleanup
moonbit docker images           # Remove unused images
moonbit docker all              # Remove all unused resources

# Find duplicates
moonbit duplicates find                    # Find duplicate files
moonbit duplicates find --min-size 10240   # Only files >= 10KB

# Backups
moonbit backup list             # List available backups
moonbit backup restore <name>   # Restore a backup

Automated Cleaning

MoonBit includes systemd timers for automated maintenance:

• moonbit-scan.timer: Scans daily at 2 AM
• moonbit-clean.timer: Cleans weekly on Sunday at 3 AM

Setup Timers

Option 1: Using the TUI (Recommended)

moonbit  # Launch TUI and select "Schedule Scan & Clean"

The TUI allows you to enable/disable timers and view their current status with a simple interface.

Option 2: Using the Installer

sudo ./moonbit-installer  # Select timer schedule during installation

Option 3: Manual Setup

# Enable and start scan timer
sudo systemctl enable --now moonbit-scan.timer

# Enable and start clean timer
sudo systemctl enable --now moonbit-clean.timer

Check Timer Status

# View active timers
systemctl list-timers moonbit-*

# Check service logs
journalctl -u moonbit-scan.service
journalctl -u moonbit-clean.service

Customize Timer Schedule

sudo systemctl edit moonbit-scan.timer
sudo systemctl edit moonbit-clean.timer
