What is VI / VIM Editor?

VI / VIM is the default text editor that is provided on the Linux platform. It can be quite intimidating to use but make no mistake – VI is an extremely powerful tool!

Example of the vi / VIM editor in Linux

What makes VIM different

VIM is split into several modes that each have different purposes. VIM starts in “normal” mode by default. However, you can use the keys below to enter the desired mode and press Esc to return to normal mode.

Here is a description of some of the modes in VIM, using the most common commands:

Normal mode – This mode allows you to open a file and move around in it. You can use the cursor keys to move around, or you can use h (left), j (down), k (up), and l (right) to move as well.

Insert mode – As the name suggests, this mode allows you to insert text. Using the ‘i’ key will switch the editor into insert mode. Similarly, the ‘a’ key will switch the editor into append mode after the current character position. Finally, the ‘o’ key inserts a new line below the current line and enters insert mode on the new line.

Visual mode – This is used to make selections of text rather than “viewing” per se. Press the ‘v’ key to enter the visual mode. Doing so will also mark a starting selection point. Now move the cursor until the desired end selection point. Remember to press Esc to return to normal mode.

Command mode – To enter command mode press ‘:’ and then type your command. Your command will appear at the bottom of the window.

Here are some basic commands you may want to use:

  • :h or :help will show you the help file.
  • :w will save the changes without exiting from the editor window.
  • :wq will both save the changes and exit from the editor.
  • :q use on its own will discard the changes you have made.

Practical examples

Open/create a file

For example, run the following command to open/create a file:

vim filename

If the file already exists, then you can edit that file. Moreover, If no file exists with this name, then it will create a new file.

Insert data into a new or existing file

When you run the command vim filename, an editor window will open.

Follow these steps to write data into a new or existing file.

  1. Press i to enter the insert mode
  2. Write any data you want to write to that file
  3. After you have written the data, press esc key to get out of the insert mode (to go back to normal mode)
  4. Press :w to save the changes without exiting from the editor window. Here, w means writing the changes to the disk
  5. Press :wq to both save the changes and exit from the editor. Here, w means you want to write changes to disk and q means you want to exit from the editor window.
  6. However, if you want to discard the changes you have made then press :q alone instead of :wq
  7. If :wq gives error then press :wq!

The above steps will remain the same whether the file already exists or you create a new file.

Create a file by inserting the data on the terminal/stdin

Follow the following steps if you want to write data from the terminal/stdin to a file.

  1. vim –
  2. When you run this command you will get a message like Vim: Reading from stdin… Now, you can write data to this file
  3. After you write the data, press ctrl+d (it will take you to the editor window)
  4. Press :wq filename to both save the changes and exit from the editor
  5. If :wq filename gives error then press :wq! filename

Append data to a particular line of the file

After opening the file using vim filename command, take the cursor to any line and press shift+a.

When you press shift+a, the cursor position will be set to the end of that particular line. You can then you can add data.

After adding the data, you can use again :wq or :wq! to save the changes and exit from the editor.

Delete data from a file

To delete the data character by character, first, open the file by vim filename command. Then, after opening the file, press x by taking the cursor on the character you want to delete.

To delete any word, take the cursor on the top of that word and press dw. Moreover, you can also delete to the end of the line by pressing the d$.

You can delete a line completely by pressing dd.

Here, d means you want to delete something, and w or $ determines the length for which you want to perform the deletion.

You can also delete all the contents of a file by using the following command:


Where 1 is the starting position, $ is the ending position, and d means delete.

Set the cursor position in the file

One way to move the cursor is to use the arrow keys. You can also use many other shortcuts to move around the file at different positions e.g.

  • Press 3w to move the cursor 3 words forward
  • Press 5e to move the cursor to the end of the 5th word in the forward direction
  • Press 0 to go to the start of the line
  • Press shift+g or :$ to go to the end of the file
  • Press gg to go to the first line

Copy and paste data

To copy any line, press yy by taking the cursor to any position of any line.

To paste the already copied line, press p by first going to the normal mode(pressing ESC).

Moreover, you can also copy multiple lines by pressing Nyy Where N can be any number. For instance, to copy 5 lines, we can press 5yy.

Search a string

To search any word from a file, first, open the file. Make sure you are in the normal mode (by pressing Esc). Now, press / followed by the search string e.g.


Moreover, if there are multiple occurrences of the search_string, then press n to go to the next occurrence. You can also go back to the previous occurrence by pressing shift+n.

Replace a word with another word

By going to the normal mode, you can run the following command:


You can replace old_word and new_word with your own desired words. This command will replace only the first occurrence of old_word.

However, you can replace all the occurrences of old_word with new_word by the following command:


Where g means globally(to replace all the occurrences).
