If you are trying to save a file using :wq! command in Vi and you get an error - E32: No file name, well then the chances are that you are trying to write to a file, but you haven't created a file.
You may have simply opened the vi/vim editor using the command and not proving the file name.

Fix:
You will need to save the file using the command below.
Syntax::w {filename}
Example
:w {data.txt}
"{data.txt}" [New] 3L, 17B written
Now if you try to do :wq! you should not get any errors!
