How to Save a File in Vi / Vim & Exit


Introduction

Vim (Vi IMproved) is an open-source text editor for Unix and Linux systems. It is a powerful and stable tool for editing and writing text, both in the command-line interface and as an independent application in a GUI.

Take the first step in learning Vim with the basic save and exit commands. Follow this guide and learn how to save a file in Vi/Vim and exit the editor.

Prerequisites

  • A system running Linux.
  • A user with sudo privileges.
  • Access to a terminal/command line.
  • Vim installed (alternatively, use the default Vi).

Using Vim Modes

When Vim launches, files are opened in command mode by default. This means that you can move around and edit the file, but cannot insert new text.

All alphanumeric keys in this mode are equal to commands, and pressing them will not display their value on the screen. For example, pressing the letter w will move the cursor one word forward.

To type text, you must be in insert mode. To switch to insert mode, press the key. Now you can type text into a file.

To switch back to command mode, press the Esc button.

How to Save Changes in Vim

Vim offers different commands to save changes to a file, depending on whether you need to exit the text editor or not. Below are examples demonstrating how to save and exit, save without exiting, and exit without saving.

Start by opening a new text file using Vim:

Next, press i to enter insert mode and add some text.
