dvcrn Storage Cleanup
Reclaim tens of gigabytes in one command. No config files, no dependencies, no damage.
Why This Skill
Systems accumulate junk silently — IDE caches, old snap revisions, stale pip builds, forgotten trash, outdated kernels. Manually hunting them down wastes time and risks deleting the wrong thing.
This skill:
- Scans 12+ cleanup targets across both macOS and Linux in a single pass
- Safe by default —
--dry-runshows exactly what would be cleaned before touching anything - Zero dependencies — pure bash + awk, works on any stock macOS or Linux install
- Cross-platform — auto-detects OS and runs only what applies (no errors on missing tools)
- Selective — skip any category with
--skip-kernels,--skip-docker,--skip-brew,--skip-snap - Reports savings — shows before/after disk usage and exact bytes freed
Quick Start
# Preview what would be cleaned (safe, changes nothing)
bash scripts/cleanup.sh --dry-run
# Clean everything
bash scripts/cleanup.sh --yes
# Clean but keep Docker and old kernels
bash scripts/cleanup.sh --yes --skip-docker --skip-kernels
What Gets Cleaned
Both Platforms
| Target | Typical Size | Notes |
|---|---|---|
| Trash | 1–50 GB | macOS ~/.Trash, Linux ~/.local/share/Trash |
Stale /tmp |
1–10 GB | pip/npm/rust build dirs older than 60 min |
| pip cache | 50–500 MB | pip cache purge |
| Go build cache | 100 MB–2 GB | go clean -cache |
| pnpm / yarn / node caches | 50–500 MB | Safe to regenerate |
| JetBrains IDE cache | 1–10 GB | IntelliJ, PyCharm, WebStorm, etc. |
| Whisper model cache | 1–5 GB | Redownloads on demand |
| Chrome / Firefox cache | 200 MB–2 GB | Browsing cache only |
| Playwright browsers | 200 MB–1 GB | Redownloads on demand |
| Docker dangling images | 0–10 GB | Only unreferenced images + build cache |
Linux Only
| Target | Typical Size | Notes |
|---|---|---|
| Apt cache | 200 MB–2 GB | apt clean |
| Journal logs | 500 MB–4 GB | Vacuumed to 200 MB |
| Disabled snap revisions | 500 MB–5 GB | Old versions kept by snapd |
| Old kernels | 200–800 MB | Keeps current running kernel |
macOS Only
| Target | Typical Size | Notes |
|---|---|---|
| Homebrew old versions | 500 MB–5 GB | brew cleanup --prune=7 |
| Xcode DerivedData | 2–30 GB | Build artifacts, safe to clear |
| Xcode Archives | 1–20 GB | Old build archives |
| iOS DeviceSupport | 2–15 GB | Old device symbols |
| CoreSimulator caches | 500 MB–5 GB | Simulator disk images |
| Old user logs | 100 MB–1 GB | Logs older than 30 days |
