Master Vim: Essential Modes, Commands, and Tips for Linux Users

Introduction

The article provides a concise tutorial on using the Vim editor in Linux, starting with how to access Vim’s built‑in help ( :help) and then diving into its modal editing model.

Vim Modes

Vim operates with several distinct modes, each affecting how keystrokes are interpreted:

Normal mode : the default editing mode; most commands are entered here. Press Esc to return from any other mode.

Command mode : entered by typing :, /, or ? in Normal mode; commands are executed after pressing Enter.

Insert mode : for inserting text, entered with i, a, o, O, etc.

Visual mode : for selecting text blocks; v selects characters, V selects whole lines, Ctrl‑V selects rectangular blocks.

Select mode : similar to typical Windows editors; rarely used on Linux and omitted from further discussion.

Insert‑mode shortcuts

i

– insert at cursor I – insert at line start o – open a new line below O – open a new line above a – append after cursor A – append at line end

Basic Editing Operations

1. Cursor movement

In Normal mode, use the following keys: h – left j – down k – up l – right

Arrow keys work as well but are slower for touch‑typists.

2. Deleting text

x

– delete the character under the cursor dd – delete the current line u – undo the last change Ctrl‑R – redo an undone change U – undo all changes on the current line

3. Other editing commands

o

/ O – open a new line below/above and switch to Insert mode

4. Exiting Vim

ZZ

– save and quit :q! – quit without saving :e! – reload the file, discarding changes :wq or :wq! – write (save) and quit

5. Jumping to specific lines

G

– go to the last line (or {num}G to go to line {num}) gg – go to the first line (same as 1G)

6. Simple searching

/pattern

– search forward for

pattern

?pattern

– search backward n – repeat the search in the same direction; N – opposite direction :set ignorecase / :set noignorecase – toggle case‑insensitive search :set hlsearch / :set nohlsearch – enable/disable result highlighting

7. Copy and paste

y

– yank (copy) into a register; e.g., yw copies a word, yy copies a whole line, 3yy copies three lines. p – paste after the cursor (or P before).

8. Substituting text

:s/old/new/

– replace first occurrence of old on the current line :s/old/new/g – replace all occurrences on the current line :%s/old/new/g – replace all occurrences in the entire file

Vim’s Swap‑File Protection

If Vim is terminated abruptly, a swap file ( .filename.swp) is left behind. On the next start Vim warns with E325: swap file exists and offers options: (O) – open read‑only (E) – edit anyway (R) – recover changes (D) – delete the swap file (Q) – quit (A) – abort

Recover with :recover or vim -r filename, then delete the swap file to avoid future warnings.

Permissions Note

Vim requires appropriate read/write permissions on the target file; lacking them will prevent editing or saving.
