This tutorial describes how to open, edit, and save a plain text file using the Vim text editor in a command line interface (CLI).

Why Use Vim

Vim offers a rich selection of keyboard-based shortcuts that make editing, inserting, deleting, and searching for specific use-cases speedy and efficient.

Background Information

Derived from the Vi text editor, Vim stands for "Vi IMproved".

Notable upgrades include:

1. Multi-Level Undo
2. Multiple Windows Mode
3. Syntax Highlighting

Modes - Input and Command

Vim has two main modes of operation: insert and command.

1. Insert Mode

In insert mode, anything typed by the user is output to the opened file. However, the user can't give shortcut commands to alter text or return to the command line.

For example, a user would use insert mode to type up a paragraph. However, a user would and could not use insert mode to give a command like dl to delete the line the cursor is on.

Press i to enter insert mode.

Press ESC to exit insert mode and enter command mode.

Note: Insert mode can be verified if an "-- INSERT --" message is shown in the bottom-left hand corner of the screen.

2. Command Mode (Default)

In command mode, anything typed by the user is processed as shortcut commands to alter the contents of the file in some shape or form. While in command mode, Vim does not input plain text into the file itself.

For example, a user would use command mode to input a command like dl to delete the line the cursor is on. A user would not use command mode to type up a paragraph.

How to Use - The Basics

1. Create a new file and open it in Vim.
   • a. Type vim note.txt

2. Enter input mode.
   • a. Press the i key.

Note: The -- INSERT -- status message in the bottom-left corner signals that you can now insert text.

3. Write in some text.
   • a. Type in a message (Example: I love Linux.)

4. Exit insert mode.
   • a. Press the ESC key.

Note: The -- INSERT -- message has now dissapeared.

5. Save the file (write it to disk).
   • a. Type :w + ENTER

6. Exit (quit) Vim and return back to the command line.
   • a. Type :q + ENTER

Note: Alternatively, typing :wq + ENTER writes the file and quits to the command line is one step.

Advanced Command Shortcuts

The best thing about Vim are its shortcuts.

Warning: Vim is case-sensitive, meaning it interprets the same letter as two different commands based on upper or lower casing.
