"no tener más que" + infinitive

Question

What is the meaning of the modismo "no tener más que" + infinitive ?

Does it mean "all that you have to do is" ?

Is it more or less the opposite of "no tienes que + infinitive =

You don't have to do something/ you mustn't do something

Answer 1

Wouldn't it be, 'not to have more than'?

Answer 2

I've never heard this form used and couldn't really find anything online, literally, it's just as Lise-Laroche says, but I would guess that it might be meant to mean "You don't have to do anything more than..." or "All you have to do is..." Just a guess. Hope this helps.
