Installation on Debian based Linux System
Installation is quite simple and easy as compare to Windows on Linux platform. I am going to describe the step of installation on Debian based Linux.
First of all We need execute these command in terminal –
To ensure, Vim is correctly install or not. Execute below command −
It should print the location of Vim binary. In my case it was −
Vim editor has own tutorial. We can learn everything about that tutor page. You can see this tutorial by command vimtutor into the terminal .
Now, Let’s go with an example to use Vim
To open a file in vim editor, We just need to write the file name after the vim command in the terminal as follows:
After execution of this command, a editor will open.
Let’s write some content into opened file.We need to go in insert mode to write something. To go into write mode type
i as follows:-
After going into insert mode you will see INSERT in the status bar. We can write any data in it.
Save and Exit:
We have written the info or data into a file now the task is to save and close. Now first of all we have to exit from insert mode by pressing the Esc key. After Esc, use semicolon to write command ( : ) and type the command wq!, hit ENTER.
Exit without saving the file:
To exit from the file without saving, just use the command q! As follows
Moving the Cursor:
We can use the arrow keys to move the cursor into a file. As this is not recommendation to use arrow keys in vim. Vim provides the special key to move the cursor in the vim editor as below –
- k -> move up
- j -> move down
- h -> move right
- l -> move left
We can use all these option to move vim files and move the faster cursor into the files.

Text Editing: Deletion
We provide x key in command mode to delete the character under the cursor.
The character under the cursor will be delete.
Text Editing: Insertion
There are Four keys use for insertion text. Just type the key into the normal mode in vim.
- i -> This insertion key is use to put the cursor before the current position.
- a -> This key is use to put the cursor after the current position.
- o -> This key is use to put the cursor below the line.
- O -> This key is use to puts the cursor above the line.
Motions provide context to your Operators. These execute the action in a particular way.
Here is a list of some motions
- w – until the start of the next word, EXCLUDING its first character.
- e – to the end of the current word, INCLUDING the last character.
- $ – to the end of the line, INCLUDING the last character.
- We can use motion with the d key and with many more keys
Count is the number for which replete the motion for count number. Here is a demonstration of the use of count and motion
To move cursor 2 words forward use the below command
Here 2 is the number of counts and w is use for word
To move cursor 4 line forward use the below command
Always use the Esc key to go into normal mode and use the insertion, deletion keys, and other keys.
To delete the word move the cursor to the beginning of the word and use dw command in normal mode. The word under the cursor will be delete.
As we know how to delete the word under cursor. Now we will delete the a word using below command.
Use below command to delete 2 words –
Delete the complete line, move the cursor to the beginning of the line and use d$ command. The line under the cursor will be delete.
Undo and Redo:
As we are programmers, most time we are using undo and redo .vim to provide these to both features in it. To undo press u key in normal mode
To redo use the ctrl+r key in normal mode in vim
In this, We will learn how we can search a pattern in vim editor. We will use the below command to search pattern-
Now, Use n to move on next matching word
Similarly, Use N to move on previous matching word
