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

Good call. I moved the “Help grow the community!” banner below the results and collapsed it on mobile so it doesn’t crowd search. Thanks for the heads-up—refresh and it should feel a lot cleaner.

Thanks for the heads-up. I pushed a fix so the Copy button pulls from the data model (not DOM) and added a clipboard fallback for stricter browsers. Can you try a hard refresh and see if it still truncates?

If it still reproduces for them, we’ll grab their FF version and distro, but this should squash the “grep ” symptom.

Great comment, and it’s a nice on-ramp to add rsync properly.

Paste-ready reply for HN

Good call. I just added a handful of rsync recipes: • rsync -avh --progress SRC/ DEST/ (archive, human sizes, progress) • rsync -azP -e ssh SRC/ user@host:/path/ (SSH, compress, resume) • rsync -avh --delete SRC/ DEST/ (mirror with delete — ) • rsync -avh --checksum SRC/ DEST/ (checksum verify; slower) • rsync -avh --exclude='.git' --exclude='node_modules' SRC/ DEST/ (exclude patterns) • rsync -azP --bwlimit=2m -e ssh … (bandwidth limit) • bonus mnemonic: rsync -mrchivas … → m prune-empty, r recursive, c checksum, h human, i itemize, v verbose, a archive, s safe (note: -a already implies -r, and -c slows it down)

If there’s a specific rsync you reach for, drop it and I’ll add it too.

Thanks! A full CLI is on my list, but you can use Greppers as a terminal app today with fzf:

   # add to ~/.bashrc or ~/.zshrc
   gpr() {
     curl -fsSL https://www.greppers.com/data/commands.json |
       jq -r '.[] | [.title, .command, (.tags|join(","))] | @tsv' |
       fzf --with-nth=1,3 --delimiter='\t' \
           --header='type to filter • Enter=copy' \
           --preview='printf "⟪ %s ⟫\n\n%s\n" {1} {2}' \
           --bind 'enter:execute-silent(echo -n {2} | (pbcopy || xclip -selection clipboard || wl-copy || xsel -ib || clip.exe))+accept'
  }
  # usage: run `gpr`, type to filter, Enter copies the command

Great pointer—love tldr. Greppers is a different slice: • Copy-first & tiny: one or two opinionated incantations with sensible flags, not an exhaustive page. • Instant search & links: live filtering, ?q= deep links, favorites (local), and keyboard nav; easy to share a specific query. • Curation over coverage: mixes cross-tool “recipes” (e.g., lsof + networking, systemd log views) rather than a page per command. • Safety: “dangerous” commands prompt before copying.

They’re complementary: tldr is a great reference with multiple examples per command; Greppers is for the 2–3 commands you re-google at 1am with the exact flags you want to copy. If there’s a command where the tldr example is clearly better, I’ll happily mirror it or link out.

I've added this to the text at the top, so more people will see it.

Btw - if you're replying to other commenters, can you do so by clicking the 'reply' link at the end of their comment? That will place your response underneath the comment you're referencing, which will make the thread much more readable.

Currently, your comments are all going to the top level, where it's hard to connect them with the other posts you're replying to. I'm going to try to move them manually to the right places, but it's not clear what those are!
