Getting started with VIM: the Lightning Text Editor ⚡

Whatever sins this text editor may have, being slow is not one of them.
Vim is a light and powerful text editor widely used among programmers and other technical professionals who work with text regularly.

Why Vim

Vim is known for its speed and low resource consumption, making it suitable for use on older systems or in remote environments. It's often preferred by developers who work on servers or in terminal-only environments. It gives them seamless integration with the command line.
It also makes you feel like a tech-savvy.

Installing Vim

On Linux

sudo apt install vim

On macOS

brew install vim

On Windows

• Go to the Vim website: https://www.vim.org/download.php
• Under "PC: MS-DOS and MS-Windows," click on the "gvim82.exe" link (the version number may vary).
• Run the downloaded installer, and follow the on-screen instructions to install Vim.

On Android - Termux

pkg install vim

Opening Vim

• After installing Vim, type

vim

on the terminal or PowerShell, to open the text editor.

• Also use the command:

vim <FILENMAE>

to open an existing file or create a new one if it doesn't exist.

Modes in Vim

There are three essential modes in Vim, they are:

• Normal: Default; for navigation and simple editing
• Command Line: For operations like saving, exiting, searching etc.
• Insert: For explicitly inserting and modifying text

Normal mode

Use the Esc key to return to the normal mode, even if you are already in the normal mode. The mode is mainly for navigation; you can use the arrow buttons to move the cursor up ↑, down ↓, left ← and right → of your file.
It is from the Normal Mode, you can enter the Insert Mode and the Command Line Mode.

Command Line Mode

To enter the Command Line Mode, press the column character : and the Vim editor will be ready to accept your command.

Now let's have a drum roll 🥁 because we are about to finally exit Vim

HOW TO EXIT VIM

Press the keys :q! and hit <ENTER> to exit.

Yeah that's all. We made it out, FAST. You can now exit Vim.

Let's proceed.

Insert Mode

To enter the Insert Mode, just hit the letter i on your keyboard. And voila, you're in. You will always see -- INSERT -- at the bottom left of your screen whenever you are in insert mode.
This means you can now edit the file, by typing in your text.

Basic Commands

Here are some basic commands to get you rolling with Vim:

Saving and Quitting

• :w (write) - to save file
• :q (quit) - to exit and confirm if not saved
• :wq (write and quit) - to save file and exit vim
• :q! (quite forcefully) - to exit Vim whether the file is saved or not

Search and Replace Text

• /text - to search for text in the document, going forward.
• n - to move the cursor to the next instance of the text from the last search. This will wrap to the beginning of the document.
• N - to move the cursor to the previous instance of the text from the last search.
• :%s/text/replacement text/g - to search through the entire document for text and replace it with replacement text.

Copy, Paste, Undo, Redo

• v (visual mode) - to highlight one character at a time. Use the arrow keys to move the cursor and select text.
• y (yank) - to copy text into Vim's copy buffer.
• p (paste) - to paste copied text after the cursor.
• u (undo) - to undo the last operation.
• Ctrl+r (redo) - to redo the last undo.

Moving the cursor

• use ↑↓←→ up, down, left, and right arrow keys to move around
• use HOME key to go to the beginning of a line
• use Ctrl+HOME to go to the beginning of the file
• use END key to go to the end of a line
• use Ctrl+END to go to the end of a file

Next Step

This is how far I can go with you on this journey. At least, you now know how to exit (with :q! or :wq), whenever you get into trouble. Let Documentation, Trials-and-Errors, Google, and ChatGPT be your guide. You have to continue the remaining part of the journey on your own.

I wish you the best of luck 🍀
