metadata extraction

Stop drowning in tarballs: this guide pairs classic Linux tools with a local LLM to auto-benchmark and pick the right compression per filetype, skip uncompressible media, generate JSON policies and human-readable manifests, and standardize naming/retention. Includes cross-distro installs and Bash scripts, cutting storage/CPU costs and speeding backups and restores.

Build a scriptable Bash pipeline to auto-tag PDFs, notes, code, and images with AI: extract text/EXIF, summarize, request 3–5 JSON tags via OpenAI-compatible API or local Ollama, then apply them as extended attributes or symlink-based tag folders. Includes distro-specific installs, env setup, a ready-to-run script, usage examples, speed-ups, privacy/cost tips, and maintenance/caching guidance.
