## Projektgeschichte und Nutzung

defaultbrowser is a small macOS command-line utility for listing and changing the system default web browser, specifically the HTTP handler.

### Projektgeschichte

The README presents defaultbrowser as a macOS X tool built around the macOS Launch Services API. Its scope is intentionally narrow: run without arguments to list browser handlers and run with a browser identifier to set the default.

The repository has tagged commits for v1.0 in 2017 and 1.1 in 2018, matching the tool's stable, low-churn nature.

### Adoptionsgeschichte

defaultbrowser is packaged by Homebrew, which fits its audience: Mac users and automation scripts that need a terminal-friendly way to change a desktop preference normally managed through system settings.

### Wie es verwendet wird

The common usage is direct and scriptable: `defaultbrowser` shows available HTTP handlers and the current default, while commands such as `defaultbrowser chrome` set the default browser.

### Warum Paket-Nerds sich dafür interessieren

defaultbrowser is a classic package-manager utility because it wraps a platform preference in one tiny CLI. It is useful in dotfiles, setup scripts, and fleet/bootstrap workflows where opening a GUI preferences pane would be the wrong interface.

### Zeitleiste

- 2017: v1.0 tagged commit.
- 2018: 1.1 tagged commit.
- 2026: Homebrew continues to publish the formula.

### Related projects
