How is the wait pattern implemented in the Vim editor?

In the Vim editor, to save (commit) changes made, the command used is to write the file.

To save changes while in command mode (usually after pressing Esc), you need to enter:

:w

and press Enter. This will save the current file.

If you want to save and exit the editor, the command is:

:wq

or

:x

If you want to exit without saving, the command is:

:q!

Thus, to commit changes, simply execute :w.
