GH-EXTENSION(1)

💅 GH-EXTENSION(1) — like, the whole gh extensions manual, bestie

okay so real quick: this is page one of the GitHub CLI manual, and it's all about gh-extension — managing your gh extensions. buckle up 🎀

---

✨ NAME ✨

gh-extension — manage gh extensions 🧚

---

✨ SYNOPSIS ✨

gh extension [flags]

---

🦋 DESCRIPTION 🦋

So. GitHub CLI extensions are literally just repositories that give you extra gh commands. that's it, that's the vibe. 💖

The name of the extension repository must start with gh-, and it must contain an executable with that same name. every single argument you pass to the gh <extname> invocation gets forwarded straight to the gh-<extname> executable of the extension. no cap, everything gets passed along. ✨

🚨 important: an extension cannot override any of the core gh commands. if an extension name collides with a core gh command, you can still run it with gh extension exec <extname>.

When an extension is executed, gh checks for new versions once every 24 hours and shows you an upgrade notice. wanna turn those notices off? run gh help environment and it'll tell you how. 👑

Now the serious part, bestie, listen up 🫶 — extensions are not verified, signed, or endorsed by GitHub. when you install or upgrade an extension, you are trusting its publisher. it is your responsibility to review the source and provenance of any extension before you use it. like, actually. pls be careful. 😭
