New Feature: WinDirStat-like disk space analyzer for Linux
Location: modules/maintenance/disk-space-analyzer.sh
Menu: Backup & Recovery → Maintenance (option 4)
Key Features:
- 14 different analysis and cleanup options
- Inode usage monitoring (critical for detecting inode exhaustion)
- No external dependencies (bc removed, using awk for math)
- Multi-panel support (cPanel/Plesk/InterWorx)
- Interactive drill-down capability
- Preview before deletion for all cleanup operations
Analysis Types:
1. Disk usage overview with warnings (>90% critical, >75% warning)
2. Inode usage checking (often overlooked but critical)
3. Largest directories with drill-down capability
4. Largest files with type detection (log/db/archive/video/image)
5. Old log files analysis (>30 days with size totals)
6. Temporary files finder (/tmp, /var/tmp with age detection)
7. Package manager cache (yum/dnf/apt)
8. Email storage analysis (mail spools, Maildir, Maildrop)
9. Database storage (MySQL/MariaDB, PostgreSQL data dirs)
10. Backup files finder (.bak, .tar.gz, .sql with age)
11. WordPress analysis (uploads, plugins, cache by site)
12. Report generation (exports all analysis to timestamped file)
Cleanup Operations (all with preview):
13. Clean old log files (>30 days, shows preview, requires "yes")
14. Clean package cache (yum/dnf/apt, requires "yes")
15. Clean WordPress cache (per-site WP Super Cache cleanup)
Technical Improvements:
- size_to_bytes() function for human-readable to bytes conversion
- Uses awk for all floating point math (no bc dependency)
- Excludes system dirs (/proc, /sys, /dev, /run) for faster scans
- Format functions for consistent output (bytes/KB/MB/GB/TB)
- Age detection for files (shows days old)
- File type detection by extension
- Interactive menus with color coding
Safety Features:
- Dry-run preview before all deletions
- Confirmation prompts ("yes" required, not just "y")
- Size calculations shown before deletion
- First 10 files previewed in cleanup operations
Changes to launcher.sh:
- Added option 4 to Backup & Recovery menu
- Added case handler to run disk-space-analyzer.sh
- Menu text: "💿 Disk Space Analyzer - Find space issues & cleanup files"
Testing: Script is executable and ready to use
