How do I save changes after editing vi /etc/hosts?

Question

I am doing a Linux installation. I installed the system fine and am trying to change the vi /etc/hosts file. I have edited the file but am not sure how to save it.

I have --INSERT-- showing at the bottom.

Answer 1

First press ESC so you get back to command mode, then do.

:x (quit and save)

or

:w
and
:q

or

:wq

Answer 2

You can also use the shortcut Shift-Z-Z from command mode (as Anders said, press Esc to exit Insert mode and return to Command mode) to save and exit to the command prompt.
