The CLI will parse HTML input from stdin and output the redirect URL if found (it will output nothing if no URL was found).
# HTML from local file
cat index.html | parse-refresh-redirect
# HTML from URL
curl -s "https://adamjarret.github.io" | parse-refresh-redirectIf parse-refresh-redirect is not installed globally, run it with npx (ex. cat index.html | npx parse-refresh-redirect).
The exit code will be 0 if the URL was found, otherwise 1.
The CLI takes no options.
