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

65 points

9 months ago

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

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.

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

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