/cleanup-filesystem

Identify and safely clean up old/leftover files on the filesystem:

1. Find old log files: find /var/log -type f -mtime +30 -size +100M
2. Check old temp files: find /tmp -type f -mtime +30
3. Identify old backup files: find ~/backups -type f -mtime +90
4. Check for core dumps: find / -name "core.*" 2>/dev/null
5. Find large old files in home: find ~ -type f -size +500M -mtime +60
6. Check for old Docker logs: du -sh /var/lib/docker/containers/*/*-json.log
7. Find duplicate files (if fdupes installed)
8. Check package manager cache: du -sh /var/cache/apt/archives
9. Look for old downloads: find ~/Downloads -type f -mtime +90 2>/dev/null

IMPORTANT: DO NOT delete anything automatically. Only identify candidates.

Provide Daniel with:

• List of cleanup candidates organized by:
  • Old log files (with sizes)
  • Temp files past retention
  • Old backups past retention policy
  • Large old files
  • Core dumps
  • Package cache
• Estimated space recoverable for each category
• Recommended retention policies
• Safe cleanup commands for Daniel to review and approve
• Risks and considerations for each cleanup action

Require explicit approval before any deletions
