16.4 Saving -Files

- -

There are several ways to save files in vi. If you want to -save the current buffer to the file randomness, you would -type:

- - - - - -

-:w randomness
-

- -

Once you've saved the file once, saving it again is as simple as typing :w. Any changes will be written out to the file. After you've saved -the file, you are dumped back into command mode. If you want to save the file and quit -vi (a very common operation), you would type :wq. That tells vi to save the current file -and quit back to the shell.

- -

On occasion, you want to save a file that is marked as read-only. You can do this by -adding an exclamation point after the write command, like so:

- - - - - -

-:w!
-

- -

However, there will still be instances where you cannot write the file (for example, -you are attempting to edit a file that is owned by another user). When this happens, vi will tell you that it cannot save the file. If you really want to -edit the file, you'll have to come back and edit it as root or -(preferably) the owner of that file.
