Can I edit container bash text files using editor? If yes, how?

How can I edit a text file (.conf, txt, ....) inside a container using bash using editor? Which command can I use for this? Is there a built-in editor? If so which one and how can I open it via bash?

Sometimes you will find vi, vim or nano is installed in the container, other times not.

If you don't have any of those editors, you will have the built-in tool called cat.

As far as I can see, Cat only offers me the option of displaying the file or overwriting it with text, but unfortunately not editing it.
