Vim, an acronym for Vi IMproved, stands out in the world of text editors for its efficiency, flexibility, and enduring popularity, especially among programmers and system administrators. In the present day, its relevance remains unchallenged, offering a powerful set of features that facilitate quick and efficient text editing.
This blog post aims to demystify Vim for beginners and enhance the toolkit of more experienced users. From basic commands, understanding different modes, to FAQs, we’ve covered essential aspects to help you navigate and utilize Vim effectively, regardless of your experience level.
Getting started with Vim
First things first, how do you get into Vim? Simple! Just open your terminal and type
vim. This command launches Vim, and you’re greeted with its default screen. It might look daunting at first, but don’t worry, we’re here to demystify it.
Entering and exiting Vim
VIM - Vi IMproved version 8.2 ... ~ ~ ~ ~
To exit Vim (one of the infamous jokes in the programming world), simply press
Esc to ensure you’re in normal mode and type
:q!. This command forces Vim to quit without saving any changes. Speaking of normal mode, let me explain a bit about vim modes.
Understanding Vim modes
One of Vim’s unique features is its mode-based editing, which can be puzzling for beginners but offers great efficiency once you get the hang of it. Understanding these modes is crucial for effectively using Vim. Let’s break down the primary modes you’ll encounter:
When you first open Vim, you’re in Normal mode. This mode is all about navigating and manipulating text. It’s not for inserting text – think of it as your command center. Here, you can move around the file, delete text, copy and paste, and execute other commands.
As the name suggests, Insert mode is for inserting text. You can enter this mode by pressing
i while in Normal mode. Once in Insert mode, Vim functions like a regular text editor. To return to Normal mode, just press
Switching to Insert mode:
Output: Start typing your text right away.
Visual mode is for selecting text. You can enter it by pressing
v in Normal mode. Once you’ve highlighted the text, you can perform operations like cutting, copying, or formatting over this selection. Press
Esc to exit Visual mode.
Using Visual mode:
Output: Move the cursor to highlight text.
You enter Command-line mode by pressing
: in Normal mode. This mode is used for executing Vim commands, like saving files, searching, or quitting Vim. You’ll see the cursor move to the bottom of the screen where you can type your command.
Saving a file in Command-line mode:
To replace existing text, you use Replace mode. Press
R in Normal mode to enter this mode. Each character you type will replace the existing character under the cursor. It’s like overtyping in traditional text editors.
Output: Start typing to replace the existing text.
Navigating through Vim can be achieved with a few simple keystrokes. Remember, Vim is modal, which means you need to switch between different modes for different actions.
hmoves the cursor left.
jmoves the cursor down.
kmoves the cursor up.
lmoves the cursor right.
To start editing text in Vim, you need to enter the insert mode. Press
i while in normal mode.
Now, you can start typing like in any regular text editor. To stop editing and go back to normal mode, press
To save the changes you’ve made, you need to write the file. Press
Esc to ensure you’re in normal mode and type
:w. This command saves the file but keeps you in Vim.
Cutting, copying, and pasting
These are crucial commands in any editor, and Vim is no exception.
- To cut (or delete) a line, press
ddin normal mode.
- To copy a line, press
- To paste the line, press
Searching in Vim is straightforward. Press
/, type your search query, and hit
Enter. To navigate through search results, use
n for the next occurrence and
N for the previous one.
Vim is highly customizable, and that’s where its true power lies. You can start by editing the
.vimrc file in your home directory. This file allows you to set various options to personalize your Vim experience.
Here, you can set your preferences, like line numbers (
set number), syntax highlighting (
syntax on), and more.
10 basic Vim commands with practical examples
Let’s delve deeper into Vim’s capabilities with 10 more commands. These are particularly useful for everyday tasks and can significantly enhance your efficiency while working in Vim.
1. Opening a file
Description: This command opens
filename.txt in Vim. If the file doesn’t exist, Vim starts with a blank file named
2. Moving to the beginning of the file
Description: In Normal mode,
gg takes you straight to the beginning of the file. It’s an instant scroll to the top.
3. Moving to the end of the file
G takes you to the end of the file. It’s the quickest way to reach the bottom.
4. Jumping to a specific line number
Description: This command takes you directly to line 25. Replace
25 with any line number you need to jump to.
5. Deleting a single character
Description: In Normal mode, position the cursor over a character and press
x to delete it.
6. Undoing changes
Description: Made a mistake? Simply press
u in Normal mode to undo the last action. It’s a lifesaver.
7. Redoing changes
Ctrl + r
Description: If you undo too much,
Ctrl + r will redo your last undo.
8. Splitting the window horizontally
Description: This command splits your Vim window horizontally. You can open another file alongside by typing
9. Splitting the window vertically
Description: To split the window vertically, use
:vsp. It’s great for comparing files side by side.
10. Closing the current window
Description: If you have multiple windows open (due to splitting),
:q will close the current window.
Suppose you are working on a Python project and need to reference another file frequently. You can open the main file (
main.py) and then split the window to open the reference file (
:e main.py :sp utils.py
Output: You will see
main.py in the top half of the screen and
utils.py in the bottom half.
These commands showcase Vim’s versatility and efficiency. Whether it’s navigating large files, editing text, or managing multiple files simultaneously, Vim offers a command for almost every need.
