Be Right Back

brb wraps a command, waits for it to finish, then sends a completion event to one or more notification channels.

It is useful for long-running builds, tests, deploys, migrations, and data jobs where you do not want to watch a terminal the whole time.

How It Works

1. brb loads your global config.
2. It resolves channels (from default_channels or repeated --channel flags).
3. It runs your command with inherited stdin/stdout/stderr.
4. It builds a completion event (status, timing, exit code, cwd, host, command).
5. It delivers that event to each selected channel.
6. It exits with the same code as the wrapped command.
