    # Install AWS CLI v2 from source
    # Bash script to install the latest released version of the [AWS CLI v2](https://aws.amazon.com/cli/) from the distrubuted source.
    # Using this method to exectue the CLI under a MacBook M1 laptop as a native ARM binary - rather than falling back to [Rosetta](https://support.apple.com/en-au/102527). Currently the offically packaged macOS `.pkg` [doesn't support both Intel/M1 architectures](https://github.com/aws/aws-cli/issues/7252).
    # Script designed to be re-run - will blow away an existing install and re-install the latest available version.
    # > [!NOTE]
    # > This install script assumes you have installed a suitable version of [Python 3](https://www.python.org/downloads/) - has been tested against `Python 3.10.11` under macOS Sonoma `v14.6.1`.
    # ## Usage
    # ```sh
    # $ ./install.sh
    # $ which aws
    # /usr/local/bin/aws
    # $ which aws_completer
    # /usr/local/bin/aws_completer
    # $ aws --version
    # aws-cli/2.15.45 Python/3.10.11 Darwin/23.4.0 source-sandbox/arm64 prompt/off
    # ```
