Show HN: Greppers – fast CLI cheat sheet with instant copy and shareable search

11 shellsteady 1 9/6/2025, 7:18:28 PM greppers.com ↗

I kept re-Googling the same flags, so I built a tiny, fast directory of copy-ready CLI commands. It’s static (vanilla JS), instant search, keyboard nav (↑/↓ + Enter), favorites (localStorage), and linkable queries.

Examples: • grep errors → https://www.greppers.com/?q=grep%20error%20logs • list open ports (macOS) → https://www.greppers.com/?q=list%20open%20ports • show git branch graph → https://www.greppers.com/?q=git%20graph • tail with colors → https://www.greppers.com/?q=tail%20colors

Suggest a missing command: https://www.greppers.com/submit.html

I’m looking for gaps and better real-world examples. Feedback welcome.

Tech notes: static site on Netlify, no build system. Data is a JSON file; favorites persist via localStorage. Search is client-side; queries are linkable with ?q= and you can filter favorites with fav=1. Dangerous commands show a confirm before copying. Headers (HSTS, nosniff) + sitemap/robots are set.

Planned next: more commands/recipes (docker, systemctl, networking), offline PWA, and a simple import/export for favorites.

If something’s obviously missing, drop it here or via the form: https://www.greppers.com/submit.html
