The vim command in Linux is a powerful, faster text editor with advanced features. However, it isn’t suitable for novices. Even though, the nano command is easy to use but it isn’t efficient for complicated tasks. That is why professionals or advanced users look for another option and the vim command in Linux is a contender for that. It has special features like GUI mode, autocompletion, color schemes, and auto-completion. Moreover, searching and replacing, undoing, and redoing is comparatively easy in the vim command.

A. Description

The “vim” of the vim command in Linux is short of “Vi Improved”. Vi is a part of the UNIX operating systems. A large number of commands and features make Vi a powerful, versatile and efficient tool. The vim command in Linux is an upgraded form of Vi. The normal mode and insert mode of the vim command comes from the Vi text editor. However, the vim command has other modes as well like visual mode, command-line mode, Ex mode where each mode provides different functionality.

B. Syntax

The vim command in Linux can take multiple options and open multiple files. Now, the syntax of the vim command goes like the following

vim [OPTION]... [FILE]...

C. Options

The vim command in Linux has a lot of options, as I have mentioned earlier. To check them out, execute the following command in the command prompt:

man vim

Here I have listed some of the useful options for you in the following:

How to Install the “vim” Command in Linux

Firstly, I will install the vim command in Linux as it doesn’t come by default in most systems. It is a simple four-step process. To install the vim command, follow the step below:

1. At first, open a Terminal in your Ubuntu.
2. Copy the following command in the command prompt and hit ENTER:

   sudo apt-get install vim

3. Provide your password if necessary and press the ENTER button again.
4. Write the following if you get the message “Do you want to continue” and hit ENTER:

   Note: If it doesn’t work, run the command from below and start from step 2:

   sudo apt-get update

In the image, you can see my system is installing the vim command in Linux. Also, it is asking for my permission whether I really want to install it or not.

Practical Examples of the “vim” Command in Linux

In this part, I will show you some practical examples of the vim command in Linux. For demonstration purposes, I will use the same file named “myfile.txt” throughout all the examples. I have also provided the text I have used so that you can follow along with all the steps. Moreover, to learn the basic functionality of the vim command in a very short time, you can use the following command:

vimtutor

Example 1: Open a File in Vim

Now I will open a file in the vim text editor using the vim command in Linux. Remember, you can open both existing and non-existing files. If you open a non-existing file, the vim command will create a file by this name, similar to the nano command. Now do the following to open a file named “myfile.txt”:

1. Launch an Ubuntu Terminal first.
2. Insert the following command to open a file:

   vim myfile.txt

3. Press ENTER from the keyboard.

You will get an output like this. The file is open in normal mode. You cannot write on the file yet. I will show you how to enable insert mode in the next example. In the end, you will see the name of your file. If it is created for the first time,  you will see “New” as well.I executed the following command to see whether the file has been really created or not:

ls

See, there is a file named myfile.txt in the home directory of my computer.

Example 2: Enable Insert Mode in the “vim” Command in Linux

To write anything on a file using the vim command in Linux, you need to go into the insert mode first. To enable insert mode, follow the steps below:

1. Go to your Ubuntu and open a Terminal.
2. Insert the following command to open a file and press ENTER:

   vim myfile.txt

3. To enable insert mode, type “I” from your keyboard.

You will notice that now you can now write on the Terminal. Moreover, in the end, you will see “–INSERT–” which indicates that you are in insert mode.

Example 3: Save a File and Exit

If you write something on a file, you would want to save it and exit, right? Don’t worry; now I will show you how to save and exit at the same time in the vim command in Linux. You should remember that in the vim command, the colon (“:”) is used to write any commands and you need to be in the normal mode for that. Now do the following to save and exit:

1. At the beginning, open an Ubuntu Terminal.
2. Then copy the following command in the command prompt and press ENTER to open a file:

   vim myfile.txt

3. Press “I” on your keyboard and write the following:

   Welcome to Linuxsimply!

4. Press “ESC” on your keyboard to shift into normal mode.
5. Now insert the following to save and exit at the same time:

   :wq

   Note: If you want to save only, type “:w”, or only to exit type “:q”.
   

I used the command “:wq” to save and exit simultaneously. The colon is used to tell the vim command in Linux that I am going to enter a command now. The “w” is for saving the current file and the “q” is exiting from the vim editor.

6. To redo, press CTRL + R.

Firstly, you can see the “Welcome to Linuxsimply!” line.After undoing, the line is gone. The “1 change” at the end denotes that one change has been undone.Again, after redoing, the line has reappeared again. Moreover, the “1 change” at the end denotes that one change has been redone.
