Vim is a powerful text editor that is often used in programming and system administration. It is known for being fast and efficient, but it can be a bit confusing for new users. This tutorial will help you understand the basics of Vim and get started with some practical examples.
What is Vim?
Vim stands for “Vi Improved”. It is an advanced version of the older “Vi” editor. Vim is included with most Unix-based systems like Linux and macOS, and it can also be installed on Windows. Vim is used in the command line, which means you type commands to use it.
Starting Vim
To start Vim, open your terminal and type:
vim
This will open Vim in the terminal window. You will see a screen that looks like this:
This means you are in normal mode, where you can navigate and edit text.
Basic Modes
Vim has several modes, but the two most important for beginners are:
- Normal mode: For navigating and editing text.
- Insert mode: For typing text.
Switching to Insert Mode
To start typing text, you need to switch to insert mode. Press i on your keyboard. You will see “– INSERT –” at the bottom of the screen. Now, you can start typing text. For example, type:
Hello, Vim!
Switching Back to Normal Mode
To go back to normal mode, press the Esc key. The “– INSERT –” at the bottom will disappear. Now you are back in normal mode.
Saving and Exiting
To save your file and exit Vim, type the following in normal mode:
:wq
This command writes (saves) the file and quits Vim. If you want to quit without saving, type:
:q!
Basic Navigation
In normal mode, you can move the cursor using the arrow keys or these keys:
- h: Move left
- j: Move down
- k: Move up
- l: Move right
Practical Examples

:wq
Example 2: Deleting Text
