Vim Basics

Vim Basics: Getting Started

Vim is an advanced, keyboard-driven text editor that enhances the classic Unix "vi" command-line tool. It is a versatile editor used for editing both code and plain-text files efficiently. To use Vim, you'll need a Linux Mint or Ubuntu operating system with Vim 8.2 or higher installed, along with an Alacritty terminal for optimal performance.

Opening a File in Vim

Once you have Vim installed, you can open a file by typing "vim" followed by the filename. For example, if you have a folder named "hello" containing a file called "hello.txt," you can open it by typing "vim hello.txt" in your terminal.

Understanding Modes in Vim

When you open a file in Vim, you are automatically placed in Normal mode. There are three primary modes in Vim: Normal, Insert, and Command. Normal mode is the default mode, where you can view the file but cannot make changes. To enter Insert mode, press the "i" key, which allows you to type directly into the editor. To return to Normal mode, simply press the "Esc" key. Command mode is entered by pressing the ":" key while in Normal mode, where you can execute commands such as saving and quitting the file.

Navigating Modes and Saving Changes

Remember, when in Insert mode, press "Esc" to go back to Normal mode. To save your changes, also ensure you are in Normal mode. Type ":w" (without quotes) and press "Enter." To save and quit at the same time, type ":wq" (without quotes) and press "Enter." If you wish to quit without saving any changes, type ":q!" (without quotes) and press "Enter."
