Master Vim Basics: Essential Modes, Commands, and Tips for Efficient Editing

Background

Vim is a popular, full‑screen text editor widely used for development, compilation, proofreading and other text‑related tasks. It offers powerful features such as auto‑completion, navigation, highlighting and repetition, enabling faster and more efficient editing.

1. Three Modes

Vim operates in three modes:

Command mode : perform delete, copy, paste and other shortcuts.

Insert mode : edit file content.

Command‑line mode : execute commands such as search, save and quit.

2. Three Ways to Open Files

1) Open a specific file

<code>vim /test/a.txt</code>

Tip: type :wq to exit and save.

2) Open a file and move the cursor to a specific line

<code>vim +3 /test/a.txt</code>

The cursor stops at line 3 (default is the first line).

3) Open a file and highlight a keyword

<code>vim +/root /test/a.txt</code>

The string

root

is highlighted upon opening.

3. Command Mode

After opening a file, Vim starts in command mode, allowing cursor movement, copy‑paste, search‑replace and other operations.

Note: In command mode, keystrokes are interpreted as commands, not text input.
