How to add `nofollow, noindex` all pages in robots.txt?

I want to add nofollow and noindex to my site whilst it's being built. The client has request I use these rules.

I am aware of

<meta name="robots" content="noindex,nofollow">

But I only have access to the robots.txt file.

Does anyone know the correct format I can use to apply noindex, nofollow rules via the robots.txt file?

Solution

noindex and nofollow mean that you do not want any search engines like Google to crawl your website.

So, simply put the following code into your robots.txt file:

User-agent: *
Disallow: /

It means noindex and nofollow.
