How to Exit the Vi Editor and Save Your Work

HOW TO EXIT THE VI EDITOR AND SAVE YOUR WORK


Text editors are considered an important tool in the current state of software development. Some users might not have a good understanding of the different functions that control text editors, particularly Vi, or its more advanced form Vim. This is because simple questions such as “How do I save my changes?” to “How do I close the editor while making the changes?” turn into big issues. This article will demonstrate how to exit Vi while saving your work and building confidence when using this useful tool.



INTRODUCTION [UNDERSTANDING THE IMPORTANCE OF TEXT EDITORS]


Programmers and administrators find text editors fundamental tools when working with the Linux operating system. Text editors are not directly related to programming. They are designed to work with the framework or language of your choice.

Text editors have been present almost from the inception of computers. They were to become an additional type of input and output device for the processor as it related to software and data. It made them capable of deleting and rewriting data with only an entire line of text. This is because terminals at that time included typewriter-like devices. With the increased use of computer terminals, what marked the beginning of screen-based text editors were the O26 computer program (1967) and the editor of Unix operating systems (1976). These are still part of the default installation of many distributions.

Today, editors are still rather simple programs that mostly serve as viewers and text file editors. But modern programs have various other options that are rather helpful to the users. These features include the use of:

● search engines;
● auto-suggested codes;
● highlighting feature.

GNU Nano editor is a popular command-line text editor included in most Linux distributions. Nano users appreciate its simple interface and dedicated keystrokes for straightforward text editing tasks. Another well-known classic text editor, Vim, stands out for its great variety of functions and is available for different platforms.

IMPORTANCE OF TEXT EDITORS IN CODING AND SCRIPTING


Text editors facilitate the creation, editing, and administration of data in code and scripts. Unlike Microsoft OS, Linux is dominated by the command line interface, so a proper text editor is a must for productivity.

● Сonvenience and speed. From the context above, one can readily appreciate how text editors enable authors to write code quickly, especially when handling large projects.

● Functionality. Current editors help users manage code and typing mistakes with such tools as syntax highlighting autocompletion, and error detection.

● Project management. Managing your project files and directories and keeping track of your program versions is made easier with the help of text editors.

● Automation of tasks. Most editors offer the option for creating macros and scripts to make otherwise time-consuming and monotonous actions.

● The ability to collaborate. It allows many programmers to work together on a particular project and manage the changes and versions that have been made.

VI AND VIM AS PREFERRED TOOLS AMONG LINUX USERS


Other tools of the Vi family, and particularly Vim, continue to be the applications for system administrators and DevOps, primarily in Linux and Unix contexts. This fact can be attributed to their installation on virtually every Unix system by default and by the freeness of benefits they provide. To say more, Vi, the application with the dramatically simple interface, and Vim, its improved copy, are the applications that many developers cannot imagine their work without.



GETTING TO KNOW VI AND VIM EDITORS [INTRODUCTION TO VI AND VIM]


An Overview of the Vi Editor


Vi is one of the oldest text editors which has gradually evolved and has become the standard for Unix and Linux VPS. It was created in 1976 by Bill Joy and has retained its position as a favorite due to its effectiveness and spartan interface. Vim provides more than 500 programming languages and contains integrated syntax highlighting.

Description and history of Vi


Vi was designed in the context of an add-on for the conventional text editor. The surveys of Stack Overflow show that developers regularly use Vim among the most popular editors.

Originally, Vim was developed for Unix-based systems, but it is now available for virtually all modern operating systems, such as Linux, Mac OS X, Microsoft Windows, and others. There are versions of Vim for mobile operating systems and Web versions; this means the possibilities of using it are considerably wider.

MODES: NORMAL, INSERT, COMMAND-LINE


Vi operates in several modes, each designed for a specific task:

● Normal mode. Commands for editing text are performed.

● Insert mode. You can input new text.

● A command line. A useful tool for typing commands such as saving and exiting.

AN OVERVIEW OF THE VIM EDITOR


Vim editor (Vi Improved) was developed in 1991 by Bram Moolenar, and it is considered an improved version of Vi. It is more powerful and flexible than the previous version. Some of Vim's benefits include the active community and many plugins/extensions. It comes with several other features and improvements, such as:

● syntax highlighting;

● extended configurability;

● plugin support;

● multi-level undo/redo;

● extensive documentation (a great resource for users looking to master this editor).

The Vim-plug repository currently has more than 15,000 plugins available. Many developers prefer Vim for its dedicated command-line interface, which allows for efficient text manipulation.

KEY FUNCTIONALITIES AND IMPROVEMENTS OVER VI


Vim offers several key improvements over Vi, including:

● Support for plugins enables functionality to be expanded.
● The readability and understanding of code are improved by syntax highlighting.
● Simultaneous editing of multiple files is possible due to multithreading functionality.
● The advanced commands enable easy and fast page and text manipulation.

PREREQUISITES


The Vim community is dedicated to continually improving the editor, adding new features and enhancements regularly. Before diving into saving files, ensure you have the necessary setup and requirements:

● Basic Knowledge. Knowledge of the fundamental directives and settings of the programs Vi/Vim.

NECESSARY SETUP AND REQUIREMENTS


Vi and Vim are usually installed by default on most Linux distributions. If not, you can add them using your system's package manager.

UNDERSTANDING COMMAND AND INSERT MODES


There are two main modes in Vi and Vim:

● Command mode. This is where you get things done with Linux command editing, navigation, and overall file management.

● Insert mode. This is where you type in content in the actual document.

HOW TO SWITCH BETWEEN MODES


You can switch between Insert and Command modes using the following commands:

INSERT MODE: Press i.

COMMAND MODE: Press Esc.




ENTER THE COMMAND MODE [PREPARING TO SAVE OR QUIT]


INSTRUCTIONS TO ENSURE YOU ARE IN COMMAND MODE


To confirm that you are in the Command mode, press the Esc key. The client is in command mode if you hear a beep or see a cursor blinking on the extreme left of the lower side.

:w — save changes.

:wq — save changes and exit.

:w file_name — save the file under a new name.

:q! — exit without saving changes.


ENCOURAGEMENT TO PRACTICE FOR PROFICIENCY


Vim is highly efficient and does not require many resources, so that it can be easily run on servers and other computing resources with limited capabilities. It can handle many commands, and the program is an excellent text editing tool. Vi stands for built-in functionality. It is quite old and has yet to be altered significantly for decades. Many Unix administrators are dedicated users of the Vi editor for its reliability and efficiency in managing system configurations.

It will help if you use these editors frequently so that learning their proper functionality and features will take less time and improve your productivity.
