I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You tried to leave the vi  / vim editor with "q" despite of the fact that you made changes to the file you opened.

You have 2 options:

- enter "q!" to quit and discard the changes

- enter "wq!" to save the changes and quit

That message means you are trying to quit the vi editor without saving changes to the file.

If you want to quit without saving, do:

:q!

If you want to save the changes, do:

:wq

:wq! => save the file and quit forcefully.
:q! => Without save and quit forcefully
