VPS Cleanup

Systematic approach to cleaning up VPS disk space — analyze files, categorize by importance, safely delete temporary/old data without losing critical files.

When to Use

• User asks "apa yang gak penting?" or "what can I delete?"
• Disk space running low (> 80% used)
• Home directory cluttered with temporary files
• After completing projects (cleanup workspace)

Workflow

Phase 1: Analyze Current State

# Check disk usage
df -h /

# Analyze home directory
cd /home/ubuntu
du -sh * 2>/dev/null | sort -h

# Check large directories
du -h --max-depth=1 | sort -h | tail -20

Phase 2: Categorize Files

For each file/directory, assess:

Phase 3: Build Decision Matrix

Create analysis table:

files = {
    'file.zip': {
        'size': '135M',
        'type': 'backup',
        'keep': True,
        'reason': 'Important backup'
    },
    'temp-workspace/': {
        'size': '538M',
        'type': 'workspace',
        'keep': False,
        'reason': 'Temporary analysis, reports done'
    },
    # ... more files
}

Calculate:

• Total size
• Deletable size
• Keep size
• Percentage reclaimable

Phase 4: Present Analysis

Show user:

1. Summary stats (total, keep, delete, %)
2. Keep list (sorted by size, with reasons)
3. Delete list (sorted by size, with reasons)
4. Recommendations (phased approach)

Format:

✅ KEEP (IMPORTANT)
  135M  backup.zip        Important backup
  2.4M  snap/             System directory

❌ CAN DELETE (NOT IMPORTANT)
  538M  temp-workspace/   Temporary, work done
  1.2M  diagrams/         PNGs generated

Phase 5: Confirm with User

CRITICAL: Always confirm before deleting, especially for:

• Large directories (> 100 MB)
• Project directories (might have uncommitted work)
• Anything user-created (not system files)

Ask:

• "Mau gue delete sekarang?" (Want me to delete now?)
• "Ada yang mau keep?" (Anything you want to keep?)

Phase 6: Safe Deletion

# Delete directories
rm -rf ~/temp-workspace/
rm -rf ~/old-project/

# Delete files
rm ~/old-archive.tar.gz
rm ~/report.md

# Verify
ls -lh ~/
df -h /

Safety checks:

• Use rm -rf only for confirmed directories
• Delete one category at a time (easier to undo if mistake)
• Verify disk space freed after deletion

User Preference Patterns

For "Delete All Unimportant"

When user says "delete semua yang gak penting" or "delete all unimportant":

DO:

• ✅ Analyze and categorize first
• ✅ Present full list with reasons
• ✅ Ask about ambiguous items (projects, large files)
• ✅ Delete after confirmation

DON'T:

• ❌ Delete immediately without analysis
• ❌ Skip showing what will be deleted
• ❌ Delete backups or system files
• ❌ Delete active projects without asking

For Safety Confirmation

When presenting cleanup plan, user may respond:

• "Aman di bersihkan?" (Safe to clean?) → User wants reassurance
• ✅ Confirm: "100% AMAN" + list what won't be deleted
• ✅ Explain worst-case scenario (e.g., "cache can be regenerated")
• ✅ Emphasize zero data loss
• ✅ Then ask: "Gas cleanup?" (Ready to proceed?)

• "Ya" (Yes) → Proceed immediately
• ✅ Execute cleanup commands
• ✅ Show progress for each step
• ✅ Verify results (before/after disk usage)
• ✅ Celebrate success: "✅ Cleanup complete! Freed XMB"

User's decision-making pattern:

1. Asks for analysis → wants to see what's unused
2. Asks "aman?" → wants safety confirmation
3. Says "ya" → ready to execute
4. Expects immediate action after confirmation (no further questions)

For Ambiguous Items

Projects (e.g., oh-my-china/):

🟡 AMBIGUOUS: oh-my-china/ (340 MB)
   Type: Project
   Question: "Masih aktif develop atau cuma testing?"
   
   If active → KEEP
   If testing → DELETE

Generated outputs:

🟡 OPTIONAL: diagram.png (4 MB)
   Type: Output
   Question: "Masih perlu atau gak?"
   
   If needed → KEEP
   If done → DELETE

Common File Types

Temporary Workspaces (DELETE)

Patterns:

• -analysis/, -test/, *-workspace/
• Cloned repos for one-time analysis
• Temporary diagram folders

Indicators:

• Reports already generated
• Work completed
• No uncommitted changes

Example:

hermes-analysis/  # 538 MB
├─ 10 cloned repos
├─ ANALYSIS_REPORT.md (done)
└─ install script (used)

→ DELETE (reports done, repos installed elsewhere)

Old Archives + Extracted (DELETE)

Pattern: Both .tar.gz AND extracted folder exist

Example:

gmail_research/              # 100 KB (extracted)
gmail_research_2026-05-01.tar.gz  # 20 KB (archive)

→ DELETE BOTH (duplicate, old data)

Temporary Reports (DELETE)

Patterns:
