I have not heard of yes. It sounds like it just repeats a string infinitely. What would be a common use case? Or is it intended to be a lego brick for bigger composed commands?

You pipe it as standard input to a command that asks you lots of yes/no questions on the command line to save on typing yes repeatedly. A lot of tools have their own command line flag to do this, e.g. apt-get has -y or --assume-yes

  Wouldn't you normally need to use "expect" or equivalent for this?

    If you wanted to vary based on the input prompt, or if the application got confused. expect is basically the next step up from yes for this use.

In addition to actually answering interactive prompts, it can be useful to test software that reads and processes stdin.
