GitHub CLI 2.0 introduces extensions
GitHub has launched GitHub CLI 2.0, a new version of its command line tool that allows developers to create extensions, or custom commands that build on CLI functionality.
The open source tool, which brings GitHub to a terminal, can be installed from cli.github.com.

With GitHub CLI 2.0, unveiled August 24, extensions are just repositories prefixed with
gh- that contain an executable file such as a Bash script. GitHub has built tools into GitHub CLI such as
gh extension create, which provides a scaffolded repository with pre-written Bash.
To help developers get started, the GitHub team built a few extensions ranging from GitHub-focused utilities like
gh contribute, for working on an open source project, to terminal-focused tools like
gh screensaver. Other GitHub CLI extensions include:
h user-status, to quickly set GitHub user status from the terminal to let others know of availability or if the user is in focus mode.
gh branch, a fuzzy finder branch switcher that orders branches by recency and displays information about associated pull requests.
gh triage, which takes GitHub’s process to triage issues in its open source repo and makes it more broadly usable.
Developers can discuss the extensions they build via a GitHub discussion thread. GitHub CLI 1.0 was released last September. The tool is intended to provide a seamless developer experience, leveraging features such as GitHub Actions to automate workflows.
