Maybe this thread is the right place to ask a usage question: I have a multiline GitHub Secret which I would like to print out to a `.env` file in a GitHub Action. How can I do that?

My current solution doesn't support spaces within the secret content:

  - name: Write .env
    run: |
      echo $ENV_FILE | tr ' ' '\n' > .env
    shell: bash
    env:
      ENV_FILE: ${{secrets.DOTENV}}

Writing a multiline secret string directly into a file replaces all newlines with spaces. The `tr` command converts them back to newlines.
