Installation

The r2drop CLI is a standalone binary. It works on macOS and Linux (x86_64 and arm64).

---

Option 1: Homebrew (Recommended)

brew tap superhumancorp/tap
brew install superhumancorp/tap/r2-cli

This is the easiest method and handles updates automatically via brew upgrade.

---

Option 2: Quick Install Script

curl -fsSL https://r2drop.com/install.sh | bash

Installs r2drop to ~/.local/bin. Works on macOS and Linux.

---

Option 3: From the macOS App

If you already have R2Drop installed, the app can install the CLI for you.

1. Open R2Drop → Settings tab → Command Line Interface

2. Click Install CLI

The CLI is installed to ~/.local/bin/r2drop and shares the app's credentials and config.

---

Option 4: Build From Source

Requires Rust stable (rustup update stable).

git clone https://github.com/superhumancorp/r2drop.git
cd r2drop
./scripts/install-cli.sh --prefix ~/.local

---

PATH Setup

If r2drop is not found after install:

echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc

Verify the install:

r2drop --version

---

Shared State With the macOS App

The CLI and app share the same local data directory (~/.r2drop/):

• config.toml — accounts and preferences

• queue.db — upload queue

• history.db — upload history

Credentials are shared via macOS Keychain (service: com.superhumancorp.r2drop).

This means if you configure an account in the macOS app, the CLI can use it immediately — no re-authentication needed.
