Hardening the infamous `curl | bash`

Scenario: Replace risky one-liners with a safer, minimally-changed variant.

Try it locally:

# Example: verify checksum before execution
url="https://example.com/install.sh"
curl -fsSLO "$url" 
curl -fsSLO "$url.sha256"
sha256sum -c install.sh.sha256
bash install.sh

What you’ll learn: integrity checks, explicit tools, and reversible steps.

Gradually improve the pattern with pinning, checksums, and safer shells.
