BookHunter — Open-Source CLI for Downloading & Managing Ebooks

BookHunter is a lightweight, scriptable command-line tool designed for power users who want to download, organize and automate ebook collections. It treats ebook management like any other part of a devops or data workflow: reproducible, auditable and easy to integrate into cron, CI/CD or local automation stacks.

If you need a terminal-first, open-source ebook downloader and library manager that plays well with other tools, BookHunter provides search, download, metadata tagging, indexing and archival workflows. Read on for a practical guide to installing, automating and extending it in production-grade setups.

Overview — what BookHunter does and why it matters

BookHunter automates the repetitive tasks around ebook acquisition and library maintenance. Instead of clicking through websites and manually renaming files, you script queries, schedule downloads, and maintain an indexed collection with standardized metadata. That approach saves time and produces consistent archives that are easier to back up, sync and search.

The tool focuses on modularity: search adapters for different sources, a downloader that respects rate limits and robots.txt, and a pluggable metadata and converter pipeline. This lets you extend BookHunter to work with public-domain repositories, licensed vendor APIs, or your own institutional sources without rewiring your entire workflow.

Because the CLI is designed for piping and scripting, it integrates nicely with common Linux utilities and automation platforms. You can feed results directly into converters, taggers, or an ebook library manager. Want to populate an OPDS catalog or sync with Calibre? That’s what BookHunter is built to help you do reliably and repeatably.

Key features that matter

BookHunter prioritizes practical features for managing growing ebook collections: multi-source search, format selection, metadata enrichment, deduplication, and output path templating. These features make it possible to run unattended jobs that keep a digital library current and organized.

It exposes a straightforward CLI and JSON output, so you can parse results with jq, Python, or any scripting language. That JSON-first design is crucial for automation: scripts can inspect results, filter matches, and take conditional actions (convert, tag, move) without fragile screen scraping.

Security and civility are built in: configurable rate limits, request headers, and adherence to robots policies. The project encourages ethical use—automate downloads for public-domain collections or licensed feeds, but avoid scraping paywalled content unless you have rights or an API token.

  • Search & download: query multiple sources and fetch EPUB/MOBI/PDF with format preference.
  • Metadata & indexing: fetch or set ISBN, author, series, tags; output to JSON or embedded metadata.
  • Automation-ready: JSON CLI output, exit codes, cron-friendly commands and sample scripts.
  • Pluggable adapters: add sources via adapters or community plugins.
  • Archival & dedupe: filename templates, archive mode, and deduplication heuristics.

Installation & quick start

Installation paths depend on the distribution model used by the project. Typical options are installing a packaged release, using a language package manager, or building from source. For production systems, installing from a release tarball or package repository gives predictable behavior and easy upgrades.

Once installed, the CLI exposes a search command and a download command. A practical pattern is: search -> filter -> download -> tag. Most workflows are one-liners piped together, e.g., search for a title and pipe the best match to a download command that writes to your canonical ebook directory.

Example CLI usage (conceptual):

# search for "Clean Code", prefer EPUBs, then download the top match
bookhunter search "Clean Code" --source gutenberg --format epub --limit 1 \
  | jq -r '.[0].id' \
  | xargs -I{} bookhunter download {} --out "~/ebooks/epub"

Automation & integration patterns

Automation is BookHunter’s forte: schedule scans for new public-domain additions, run nightly downloads into a staging directory, convert formats, and then push to your reading device or OPDS server. Because BookHunter outputs JSON and uses predictable exit codes, you can chain it into scripts that run on cron, systemd timers, or GitHub Actions.

Here’s a simple bash script that polls a source, downloads new matches, and moves completed files to an archive folder. It’s shorthand—adapt pathing, credentials and rate limits for your environment.

#!/usr/bin/env bash
query="machine learning"
out_dir="$HOME/ebooks/machine-learning"
archive="$HOME/ebooks/archive"
mkdir -p "$out_dir" "$archive"

/usr/bin/bookhunter search "$query" --source gutenberg --format epub --limit 5 \
  | jq -c '.[]' \
  | while read -r item; do
      id=$(echo "$item" | jq -r '.id')
      /usr/bin/bookhunter download "$id" --out "$out_dir" \
        && mv "$out_dir"/*.epub "$archive/" || echo "Failed: $id"
    done

For CI/CD integration, use BookHunter in an action to rebuild an index or refresh an OPDS feed when new files land in your repository. You can also invoke converters (Calibre ebook-convert) post-download to normalize formats and embed metadata automatically.

Best practices & legal considerations

Treat source terms of service and copyright like non-functional requirements. Only automate downloads from public-domain repositories or feeds you are authorized to use. If a source provides an official API or an access token, use it instead of scraping web pages; it’s stable, supported, and less likely to break your automation.

Respect rate limits and robots.txt; configure backoff and retries in your adapter settings. Frequent aggressive crawling can lead to IP bans and harms availability for other users. For large-scale archival projects, reach out to the content provider—many have bulk access options or data dumps designed for reuse.

Maintain provenance: store source URLs, timestamps and metadata in your index. That metadata makes it possible to validate collections later, comply with licensing requirements, and track where each file originated. Use checksums and deduplication to avoid file bloat.

  • Prefer official APIs or data dumps over scraping; use tokens when available.
  • Throttle requests, respect robots.txt, and log activity for audits.

FAQ

Is using BookHunter legal?

BookHunter is a tool; legality depends on what you download. Use it only with public-domain sources, licensed feeds, or content you have rights to access. When in doubt, use official APIs or contact the content owner for permission.

Which formats and sources does it support?

Out of the box, BookHunter targets common ebook formats (EPUB, MOBI, PDF) and public-domain repositories. The adapter model lets you add source-specific connectors to consume APIs or curated feeds. Check the adapter list in the project docs for exact supported sources.

How do I automate BookHunter safely?

Automate with rate limits, retries and logging. Use tokens for authenticated APIs, schedule runs during off-peak times, and store metadata+checksums so your pipeline is auditable. Integrate with converters and indexers to keep library structure consistent.
