Vim is a powerful text editor that is used to create and edit text files. It’s an improved version of the older Unix editor, Vi. Vim is popular among programmers and system administrators for its efficiency and versatility. It operates in different modes, such as Normal, Insert, and Visual, allowing users to perform various tasks quickly.
Vim was created by Bram Moolenaar in 1991. It has evolved over the years with contributions from many developers. Vim’s speed and minimalistic design make it ideal for editing code. It’s highly customizable, with countless plugins and scripts available. Vim can boost productivity because of its keyboard-centric approach, reducing the need for mouse interaction.

Getting Started
These basic concepts and commands will help you get started with Vim.
Installing Vim
To install Vim, follow these steps.
- Linux: Use the package manager of your distribution. For Debian-based systems like Ubuntu, type sudo apt-get install vim. For Red Hat-based systems like Fedora, use sudo yum install vim. Arch Linux users can install it using sudo pacman -S vim.
- macOS: Use the Homebrew package manager. First, install Homebrew if you haven’t already by running /bin/bash -c “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)”. Then, install Vim with the command brew install vim.
- Windows: Download the installer from the official Vim website and run it. Alternatively, use a package manager like Chocolatey by running Choco install vim.
After installation, you can verify it by opening a terminal or command prompt and typing vim –version.
Basic Concepts
Vim operates in several modes, each serving a specific purpose.
- Normal Mode: This is the default mode when you start Vim. In this mode, you can navigate the text, delete or change text, and perform many other operations. To return to Normal Mode from any other mode, press Esc.
- Insert Mode: Used for inserting and editing text. You can enter Insert Mode by pressing i (insert before the cursor), I (insert at the beginning of the line), a (append after the cursor), or A (append at the end of the line).
- Visual Mode: Allows selecting and manipulating blocks of text. Enter Visual Mode by pressing v (character-wise selection), V (line-wise selection), or Ctrl+v (block selection).
- Command-line Mode: For entering commands starting with :, /, or ?. For example, :w saves the file, :q quits Vim, and :wq saves and quits. Use / to search forward and ? to search backward.
Basic Commands
Opening and Closing Files
To open a file in Vim, type vim filename in your terminal or command prompt. If the file doesn’t exist, Vim will create a new one with that name. To close Vim, you can use :q to quit, :q! to quit without saving changes, and :wq or 😡 to save changes and quit. Alternatively, pressing ZZ (Shift+Z twice) will also save and quit.
Moving Around
You can use the arrow keys for basic navigation, but Vim offers more efficient methods. Use h, j, k, and l for left, down, up, and right movements, respectively. To navigate by words, use w to move to the beginning of the next word, b to move to the beginning of the previous word, and e to move to the end of the current word.
For line navigation, 0 moves to the beginning of the line, $ moves to the end, and ^ moves to the first non-blank character. To quickly move through the document, gg jumps to the top, G to the bottom, Ctrl+u scrolls up half a page, and Ctrl+d scrolls down half a page.
Inserting and Deleting Text
To insert text, press i to insert before the cursor, I to insert at the beginning of the line, a to append after the cursor, and A to append at the end of the line. You can also use o to open a new line below the current one and O to open a new line above.
To delete text, use x to delete the character under the cursor, dw to delete from the cursor to the end of the word, dd to delete the entire line, d$ to delete from the cursor to the end of the line, and d0 to delete from the cursor to the beginning of the line.
Saving Changes
To save changes, type :w. If you want to save the file with a new name, use :w filename. To save all open files, use :wa. To save and quit, use :wq or :x. These commands ensure that your changes are not lost and allow you to exit Vim cleanly.
Intermediate Commands
Copying, Cutting, and Pasting Text
To copy text, use the y (yank) command. For example, yy yanks the entire line, and yw yanks a word. To yank a specific number of lines, use nyy, where n is the number of lines.
To cut text, use the d (delete) command. dd cuts the entire line, and dw cuts a word. You can also use ndd to delete multiple lines, where n is the number of lines.
To paste text, use the p command to paste after the cursor or P to paste before the cursor. These commands are useful for rearranging text within your document.
Undo and Redo
To undo changes, use the u command. This undoes the last change you made. To redo changes, use Ctrl+r, which redoes the last undone change. These commands help you correct mistakes quickly and efficiently.
Searching and Replacing Text
To search for text, use the / command followed by the text you want to find. For example, /word searches for the word “word” in the document. To search backward, use ?word. You can navigate through search results using n for the next occurrence and N for the previous one.
To replace text, use the :s command. For example, :s/old/new/g replaces all occurrences of “old” with “new” in the current line. To replace text in the entire document, use :%s/old/new/g. The g at the end ensures all occurrences are replaced, not just the first one on each line.
Working with Buffers and Windows
Vim allows you to work with multiple files using buffers. To open a new file in a buffer, use :e filename. To switch between buffers, use :bn for the next buffer and :bp for the previous buffer. To list all open buffers, use :ls.
Vim also supports window splitting for multitasking. To split the window horizontally, use :split or :sp. For a vertical split, use :vsplit or :vsp. You can navigate between windows using Ctrl+w followed by a direction key (h, j, k, or l). To close a window, use :q.
Advanced Commands
Macros and Scripting
Macros allow you to record and replay sequences of commands, which can save time on repetitive tasks. To record a macro, press q followed by a letter to name the macro (e.g., qa starts recording a macro named “a”). Perform the desired sequence of commands, and press q again to stop recording. To replay the macro, press @ followed by the macro name (e.g., @a). You can repeat the macro multiple times by specifying a count before @ (e.g., 5@a).
Customizing Vim with .vimrc
The .vimrc file allows you to customize Vim’s behavior and appearance. Common customizations include setting line numbers (set number), enabling syntax highlighting (syntax on), and customizing the status line (set statusline=%F%m%r%h%w\ [FORMAT=%{&ff}]\ [TYPE=%Y]\ [POS=%l,%c%V]\ [%-P]). You can also map custom key bindings in your .vimrc file. For example, to map Ctrl+s to save the file, add nmap <C-s> :w<CR>.
Using Plugins
Plugins extend Vim’s functionality. Popular plugins include NERDTree for file browsing, CtrlP for fuzzy file searching, and Vim-airline for an enhanced status bar. To manage plugins, use a plugin manager like Vundle, Pathogen, or Vim-plug. For example, to install Vim-plug, add the following to your .vimrc:
Regular Expressions in Vim
Regular expressions (regex) are powerful for search and replace operations. In Vim, regex allows for complex pattern matching. For example, to find all lines containing digits, use /\d. To replace patterns, use the :s command with regex. For instance, :s/\(\w\+\)\s\+\(\w\+\)/\2 \1/g swaps the first two words in each line. Mastering regex can greatly enhance your text processing capabilities in Vim.
Vim for Programming
Syntax Highlighting
Syntax highlighting helps in differentiating elements of the code visually. To enable syntax highlighting in Vim, simply add syntax on to your .vimrc file. Vim supports syntax highlighting for a wide range of programming languages out of the box. For example, if you are editing a Python file, Vim will automatically highlight keywords, comments, and other elements in different colors.
Code Completion
Code completion can significantly speed up coding by suggesting completions for partially typed keywords. Plugins like YouCompleteMe and Deoplete offer advanced code completion features. To set up YouCompleteMe, follow the instructions on its GitHub page. These plugins provide real-time suggestions as you type, making it easier to write accurate and efficient code.
Debugging Tools
Vim can be integrated with debugging tools to make the debugging process smoother. One popular plugin for debugging is vimspector. Vimspector allows you to set breakpoints, step through code, and inspect variables directly within Vim. To install vimspector, use a plugin manager like Vim-plug and add the following to your .vimrc:
After installing the plugin, you can start debugging by configuring your debug profile and using the provided commands to control the debugging process.
Version Control Integration
Integrating version control with Vim enhances your workflow by allowing you to manage your code repository directly from the editor. The fugitive.vim plugin is a powerful tool for working with Git in Vim. To install fugitive.vim, add the following to your .vimrc:
With fugitive.vim, you can run Git commands like :Gstatus to view the status of your repository, :Gcommit to commit changes, and :Gpush to push changes to a remote repository. This integration streamlines the process of version control, making it more efficient and accessible.
