bootstrap.sh

#!/usr/bin/env bash
# bootstrap.sh — bring a new machine up from scratch.
#
# Steps:
#   1. Detect OS flavor
#   2. Ensure git is installed
#   3. Clone utility-scripts (if not already present)
#   4. Set up dotfile symlinks
#   5. Install Ansible
#   6. Run the Ansible workstation playbook
#
# The dotfiles step (4) runs before Ansible so the shell environment is
# correct even if Ansible later fails or is run incrementally.
#
# Usage (run from anywhere, even before cloning):
#   curl -fsSL https://raw.githubusercontent.com/sfroeber/utility-scripts/main/bootstrap.sh | bash
#   -- or --
#   bash ~/GitHub/utility-scripts/bootstrap.sh
