# Download Anything

Find it. Download it. Any resource, any format.

## Toolkit

```bash
# Install all tools at once

```

| `curl` | pre-installed | HTTP requests, API calls |
| `ffmpeg` | `brew install ffmpeg` | Media conversion |
| `jq` | `brew install jq` | JSON parsing for automation |

## Decision Tree

| Want to download... | Tool / Approach |
|---------------------|----------------|
| YouTube / social media video | `scripts/dl-video.sh URL` (auto-detects Bilibili cookies) |
| Audio from any video URL | `scripts/dl-audio.sh URL` |
| Spotify playlist/album/track | `spotdl URL` |
| Images from gallery/artist page | `scripts/dl-gallery.sh URL` |
| A direct file URL (fast) | `scripts/dl-file.sh URL` (aria2, 16 connections) |
| A torrent or magnet link | `scripts/dl-torrent.sh "magnet:..."` |
| Subtitles for a video | `scripts/dl-subtitle.sh QUERY` |
| An ebook or paper | → [references/ebooks.md](references/ebooks.md) |
| A movie or TV show | → [references/video.md](references/video.md) |
| Music / game soundtracks / OST | → [references/music.md](references/music.md) |
| Software or app | → [references/software.md](references/software.md) |
| Stock images/video/audio/fonts | → [references/media-assets.md](references/media-assets.md) |
| Chinese cloud drive resources | → [references/cloud-search.md](references/cloud-search.md) |
| Online courses | → [references/education.md](references/education.md) |
| Something else / not sure | → [references/search-techniques.md](references/search-techniques.md) |

## Scripts

All in `scripts/`. Each does one thing. Compose as needed.

| Script | What it does | Key args |
|--------|-------------|----------|
| `install-toolkit.sh` | Install all CLI tools | — |
| `dl-video.sh URL [QUALITY]` | Download video (auto cookies for Bilibili) | `best`/`1080`/`720`/`480` |
| `dl-audio.sh URL [FORMAT]` | Extract audio | `mp3`/`opus`/`flac`/`best` |
| `dl-file.sh URL [OUTPUT]` | Fast multi-thread download | 16 connections via aria2 |
| `dl-gallery.sh URL [DIR] [ARGS...]` | Batch download images | extra args passed to gallery-dl |
| `dl-torrent.sh MAGNET [DIR]` | Download torrent/magnet | via aria2 |
| `dl-subtitle.sh QUERY [LANG]` | Search & download subtitles | `en`/`zh`/`ja` etc. |

## Quick One-Liners

```bash
# Best quality video
yt-dlp -f "bv*+ba/b" "URL"

# 1080p video + subtitles
yt-dlp -f "bv[height<=1080]+ba/b" --write-subs --sub-langs "en,zh" "URL"

# Extract audio as MP3
yt-dlp -x --audio-format mp3 "URL"

# Download YouTube playlist
yt-dlp --yes-playlist "URL"

# Fast file download (16 connections)
aria2c -x16 -s16 -k1M "URL"

# Download magnet
aria2c --seed-time=0 "magnet:?xt=..."

# Batch images from gallery
gallery-dl "URL"

# Spotify album → local MP3s
spotdl "SPOTIFY_URL"

# All PDFs from a page
wget -r -l1 -A "*.pdf" "URL"

# Video metadata as JSON (automation)
yt-dlp -j "URL"

# Get direct URL without downloading
yt-dlp -g "URL"
```

## Agent Automation Patterns

**Video pipeline:** `yt-dlp -j URL` → parse JSON → select format → `yt-dlp -f FORMAT URL -o OUTPUT`

**Ebook search:** Search Anna's Archive / Z-Library / 鸠摩搜书 → get download page → extract link → `aria2c`

**Bulk media:** `gallery-dl --dump-json URL` → review items → `gallery-dl -d OUTPUT URL`

**Music:** `spotdl SPOTIFY_URL` (auto YouTube match + metadata) or `yt-dlp -x --audio-format mp3 YOUTUBE_URL`

## Domain Instability

Many resource sites rotate domains. When a URL fails:
1. Search: `[site name] mirror 2026` or `[站名] 最新地址`
2. Check Reddit/Twitter for community mirror lists
3. Anna's Archive = most resilient ebook meta-search
4. For Chinese cloud search: check 网盘之家导航 for latest links
