If you are a programmer or a system administrator, you must have used the Vi editor at some point in your career. Vi is a command-line text editor that is widely used on Unix, Linux, and macOS operating systems. It is a powerful tool that provides many features to work with text files. One of the essential tasks that you need to know while using Vi is how to save and exit a file. In this article, we will discuss the Vi save and exit commands and how to use them.
What is Vi?
Vi is a text editor that was created by Bill Joy in 1976. It is a part of the Unix operating system and is available on most Unix-based systems. Vi is a modal editor, which means that it has different modes of operation. The two primary modes of Vi are the command mode and the insert mode. In the command mode, you can execute commands, navigate the file, and perform various operations on the text. In the insert mode, you can insert and edit text.
How to Save and Exit in Vi
Let’s say you have opened a file in Vi and made some changes to it. Now, you want to save the changes and exit the file. To do that, you need to follow these steps:
- Press the Esc key to enter the command mode.
- Type
:wq(write and quit) or:x(save and exit) command. - Press Enter to execute the command.
The :wq command saves the changes and exits the file. If you have not made any changes to the file, the :wq command will exit the file without saving any changes. The :x command is similar to :wq, but it only saves the changes if there are any changes made to the file.
Other Vi Save and Exit Commands
Apart from :wq and :x, there are other commands that you can use to save and exit a file in Vi. Let’s discuss them one by one.
:w
The :w command saves the changes made to the file but does not exit the file. You can use this command if you want to save the changes and continue editing the file.
:q
The :q command exits the file but does not save any changes made to the file. You can use this command if you have made some changes to the file, but you do not want to save them.
:q!
The :q! command exits the file without saving any changes made to the file. You can use this command if you have made some unintended changes to the file and want to discard them.
:wq!
The :wq! command forces Vi to save the changes made to the file and exit the file. You can use this command if you do not have write permission to the file, and you want to save the changes by force.
