# Homebrew Install
|
|
|
|
Installs Homebrew on macOS and / or Linux.
|
|
|
|
## Overview
|
|
|
|
This script installs Homebrew on macOS and/or Linux machines. The script:
|
|
|
|
1. Ensures Homebrew is not already installed
|
|
2. Installs Homebrew headlessly if sudo privileges are already given
|
|
3. Prompts for the sudo password, if required
|
|
4. Performs some clean up and update tasks when the Homebrew installation reports an error
|
