To save and quit the vi or vim text editor, you can use the :wq command. The :wq command stands for "write and quit," and it writes the current file to disk and exits the editor.
To use the :wq command, you can enter it at the vi or vim command prompt. For example:
:wq
This will write the current file to disk and exit the editor.
If you have made changes to the file but have not saved them, vi or vim will prompt you to confirm that you want to save the changes before quitting. You can enter y to save the changes and quit the editor, or n to discard the changes and quit the editor.
If you want to save the changes but remain in the editor, you can use the :w command to write the changes to disk without quitting the editor. For example:
:w
This will write the changes to disk, but will not exit the editor. You can then make additional changes or use the :q command to quit the editor without saving the changes.
To force vi or vim to quit without saving the changes, you can use the :q! command. This will quit the editor and discard any unsaved changes.
By using the :wq, :w, and :q! commands, you can save and quit the vi or vim text editor and manage the changes that you have made to the file. You may want to refer to the vi or vim documentation or online resources for more information about these commands and other text editing features of vi and vim.
