Question

To save a file in the vi/vim editor which mode must you be operating in?

undo mode
command mode
edit mode
insert mode

Answer 1

In the vi/vim editor, a file can only be saved when in command mode, which is accessed by pressing the Escape key after editing, then using the :w or :wq commands.

Step-by-step explanation:

To save a file in the vi/vim editor, you must be in command mode. The vi editor has several modes, but when it comes to saving files or executing any other commands, it is essential to be in command mode. After editing the file in insert mode, you exit to command mode by pressing the Escape key (Esc). You then save the changes to the file by typing :w followed by pressing Enter. If you wish to save the file and exit the editor at the same time, you can type :wq. It's important to note that you cannot save a file while in insert mode or any mode other than command mode.
