Complete Vi/Vim editor guide. From exit methods to modes, navigation, editing, search, and replace - all practical commands.

Introduction: “Opened Vim but Cannot Exit!"

"Connected to server but no GUI editor”

When you SSH into a server, there’s no GUI editor. Vi/Vim is an essential text editor pre-installed on almost all Linux/Unix systems.

But when you first open Vim:

  • Cannot type text
  • Don’t know how to exit
  • Mouse doesn’t work
  • Commands are unusual

What This Guide Covers:

  • Exit in 10 seconds (most searched question)
  • Mode concept (Normal, Insert, Visual, Command)
  • Practical commands (navigation, editing, search, replace)
  • Essential settings (.vimrc)
  • Cheat sheet

2. Vi vs Vim Difference

Vi (Visual Editor)

  • Developed in 1976 (almost 50 years ago!)
  • Pre-installed on all Unix/Linux
  • Minimal features

Vim (Vi IMproved)

  • Developed in 1991 (improved Vi)
  • Additional features:
    • Syntax highlighting
    • Multiple undo/redo
    • Plugin system
    • Split windows
    • Auto-completion
    • Visual mode

3. Understanding Modes

Vim’s Core: Modes

Vim is a modal editor. Same key behaves differently depending on mode.

1. Normal Mode (Default)

  • Vim starts in this mode
  • Execute commands (navigate, delete, copy)
  • Cannot type text
  • ESC returns here anytime
# Normal mode commands
dd    # Delete current line
yy    # Copy current line
p     # Paste
u     # Undo

2. Insert Mode (Input)

  • Text input mode
  • Type like normal editor
  • ESC returns to Normal mode
# Enter Insert mode
i     # Insert at cursor
I     # Insert at line start
a     # Append after cursor
A     # Append at line end
o     # Open line below
O     # Open line above

3. Visual Mode (Selection)

  • Text selection mode
  • Select block then copy/delete
v       # Character-wise selection
V       # Line-wise selection
Ctrl+v  # Block-wise selection (vertical)

4. Command Mode (Commands)

  • Starts with :
  • Save, quit, search, replace
:w      # Save
:q      # Quit
:wq     # Save and quit
:%s/old/new/g  # Replace

4. Basic Navigation

hjkl Instead of Arrow Keys

# Basic movement (arrow keys work but hjkl is faster)
h    # ← Left
j    # ↓ Down
k    # ↑ Up
l    # → Right

Why hjkl?: 1970s keyboards had no arrow keys when Vi was created!

Word Movement

w    # Next word start
W    # Next word start (space-separated)
e    # Next word end
E    # Next word end (space-separated)
b    # Previous word start
B    # Previous word start (space-separated)

Line Movement

0    # Line start
^    # Line start (excluding spaces)
$    # Line end
gg   # File start
G    # File end
:n   # Go to line n (e.g., :42)
42G  # Go to line 42

Screen Movement

Ctrl+f   # Page down (forward)
Ctrl+b   # Page up (backward)
Ctrl+d   # Half page down
Ctrl+u   # Half page up
H        # Screen top (High)
M        # Screen middle (Middle)
L        # Screen bottom (Low)

5. Text Editing

Delete

x     # Delete character at cursor
X     # Delete character before cursor
dd    # Delete current line
D     # Delete from cursor to line end
dw    # Delete word
d$    # Delete from cursor to line end
d0    # Delete from cursor to line start
dG    # Delete from cursor to file end
dgg   # Delete from cursor to file start

Change

r     # Replace character (1 char)
R     # Replace mode
cw    # Change word
cc    # Change line
C     # Change from cursor to line end
s     # Delete char and enter insert mode
S     # Delete line and enter insert mode

Undo/Redo

u        # Undo
Ctrl+r   # Redo
.        # Repeat last command

6. Search and Replace

/pattern    # Search forward
?pattern    # Search backward
n           # Next match
N           # Previous match
*           # Search word under cursor
#           # Search word under cursor backward

Example:

/error      # Search "error"
n           # Next error
N           # Previous error

Replace

:s/old/new/        # Replace first old with new in current line
:s/old/new/g       # Replace all old with new in current line
:%s/old/new/g      # Replace all old with new in entire file
:%s/old/new/gc     # Replace all with confirmation
:5,10s/old/new/g   # Replace in lines 5-10

Practical Examples:

# Change print to logging in Python
:%s/print(/logging.info(/g

# Replace tabs with 4 spaces
:%s/\t/    /g

# Remove trailing spaces
:%s/\s\+$//g

7. Copy, Paste, Delete

Copy (Yank)

yy    # Copy current line
Y     # Copy current line (same as yy)
yw    # Copy word
y$    # Copy from cursor to line end

# Split empty window
:split    # Horizontal
