Vim is not just a text editor—it's a way of life for developers, system administrators, and power users around the world. What appears initially as a cryptic, arcane relic becomes, with practice, the most efficient text manipulation tool ever conceived. This comprehensive guide will take you from confusion to mastery, revealing why decades after its creation, Vim continues to be one of the most powerful weapons in a power user's arsenal.

Introduction: Why Vim?

Vim (Vi IMproved) is a highly configurable text editor built to enable efficient text editing. Originally created by Bram Moolenaar as an improved version of the Unix editor Vi, Vim has evolved into one of the most powerful text editors available.

Why should you master Vim?

1. Ubiquity: Vim is available on virtually every Unix-like system. Learning Vim means you'll never be without a familiar, powerful editor.
2. Efficiency: Once mastered, editing text in Vim is incredibly fast. Tasks that require multiple steps in other editors can be accomplished with a few keystrokes.
3. Keyboard-centric: Vim minimizes mouse usage, keeping your hands on the keyboard where they're most efficient.
4. Customizability: Vim can be tailored to your exact needs through extensive configuration options and plugins.

5. Longevity: The skills you develop in Vim will serve you for your entire career. Unlike many modern tools, Vim's core concepts have remained relatively stable for decades.

   Let's embark on this journey to transform how you interact with text forever.

Installation

Getting Started: The Essentials

#to open vim, simply type vim followed by the filename to open
vim myfilename.txt

#to go into edit mode press the letter i
i
#now add some text or edit text

#to get out of edit mode press ESC

#To exit Vim (saving changes):
#Press Esc to ensure you're in normal mode
#Type :wq and press Enter (write and quit)
:wq

#To exit without saving:
#Press Esc to ensure you're in normal mode
#Type :q! and press Enter (quit, discard changes)
:q!

Understanding Vim's Modes

Vim's power comes from its modal nature. Most editors are always in "insert mode" - what you type appears as text. Vim separates editing actions into different modes:

Normal Mode (Command Mode)

• The default mode when you start Vim
• Where you navigate and manipulate text
• Press Esc from any other mode to return to Normal mode

Insert Mode

• For inserting/typing text

• Enter from Normal mode with:

  • i - insert at cursor
  • I - insert at beginning of line
  • a - append after cursor
  • A - append at end of line
  • o - open new line below
  • O - open new line above

Visual Mode

• For selecting text

• Enter from Normal mode with:

  • v - character-wise visual mode
  • V - line-wise visual mode
  • Ctrl+v - block-wise visual mode

Command-Line Mode

• For executing commands

• Enter from Normal mode by typing :, /, or ?

  Understanding these modes is fundamental to mastering Vim. The real power comes from the seamless transitions between them.

Essential Navigation Commands

Basic Movement

• h - move left
• j - move down
• k - move up
• l - move right

Word Movement

• w - move forward to the beginning of the next word
• e - move forward to the end of the current/next word
• b - move backward to the beginning of the current/previous word

Line Movement

• 0 - move to the beginning of the line
• ^ - move to the first non-blank character of the line
• $ - move to the end of the line

Document Movement

• gg - move to the beginning of the file
• G - move to the end of the file
• :{number} - move to a specific line number
• {number}G - move to a specific line number

Screen Movement

• Ctrl+f - page down (forward)
• Ctrl+b - page up (backward)
• Ctrl+d - half page down
• Ctrl+u - half page up
• zz - center the cursor on the screen
• zt - position the cursor at the top of the screen
• zb - position the cursor at the bottom of the screen

Special Movements

• % - jump to matching bracket/parenthesis
• * - search for the word under the cursor (forward)
• # - search for the word under the cursor (backward)
• f{char} - move to the next occurrence of character {char} on the current line

• F{char} - move to the previous occurrence of character {char} on the current line

  Practice these movements until they become second nature. Efficient navigation is the foundation of Vim mastery.

Text Editing Fundamentals

Basic Insertion

• i - insert before cursor
• a - append after cursor
• I - insert at beginning of line
• A - append at end of line
• o - open new line below and enter insert mode
• O - open new line above and enter insert mode

Basic Deletion

• x - delete character under cursor
• X - delete character before cursor
• dd - delete current line
• D - delete from cursor to end of line

Copy and Paste

• yy or Y - yank (copy) current line
• p - paste after cursor
• P - paste before cursor

Undo and Redo

• u - undo last change
• Ctrl+r - redo last undone change

Change (Delete and Insert)

• cw - change word (deletes from cursor to end of word and enters insert mode)
• C - change to end of line (deletes from cursor to end of line and enters insert mode)
• cc - change entire line (deletes line and enters insert mode)
• c{motion} - change text that the motion command would move over

Text Objects

Vim has the concept of "text objects" which allow you to operate on chunks of text:

• iw - "inner word" (the entire word under the cursor)

• aw - "a word" (the word plus surrounding whitespace)

• is - "inner sentence"

• as - "a sentence"

• ip - "inner paragraph"

• ap - "a paragraph"

• i( or i) - "inner parentheses"

• a( or a) - "a parentheses" (including the parentheses)

• i{ or i} - "inner curly braces"

• a{ or a} - "a curly braces" (including the braces)

• i" - "inner quotes"

• a" - "a quotes" (including the quotes)

  Text objects are used with operators. For example:

• diw - delete inner word

• ci" - change inner quotes

• ya) - yank a parentheses (including parentheses)

Advanced Text Manipulation

Operators

Vim's power comes from combining operators with motions and text objects. The main operators are:

• d - delete

• c - change (delete and enter insert mode)

• y - yank (copy)

• > - indent right

• < - indent left

• = - auto-indent

• g~ - swap case

• gu - make lowercase

• gU - make uppercase

  Pattern: {operator}{count}{motion}

  Examples:

• d2w - delete two words

• y3j - yank three lines down

• >ap - indent a paragraph

• gUiw - uppercase inner word

Repeating Commands

• . - repeat last change
• @: - repeat last command-line command

Macros

Macros let you record a sequence of commands to replay later:

1. q{register} - start recording to register (a-z)
2. (perform your commands)
3. q - stop recording
4. @{register} - play back the macro

5. @@ - repeat the last played macro

   Example:

• qa - start recording to register 'a'
• (perform some edits)
• q - stop recording
• @a - play back the macro
• 5@a - play back the macro 5 times

Advanced Text Transformation

• guu - make entire line lowercase
• gUU - make entire line uppercase
• g~~ - swap case of entire line
• >G - indent from current position to end of file
• =G - auto-indent from current position to end of file

Marks

Marks allow you to save positions and jump back to them later:

• m{a-zA-Z} - set mark at current position

  • Lowercase marks (a-z) are file-specific
  • Uppercase marks (A-Z) are global across files
• `{mark} - jump to the exact position of mark
• '{mark} - jump to the beginning of the line containing mark

Registers

Vim has multiple registers for storing text:

• "{register} prefix before a command to specify register

• Registers a-z: named registers for user storage

• Register 0: contains the last yanked text

• Registers 1-9: contain the last deleted or changed text

• Register +: system clipboard (OS dependent)

• Register *: selection clipboard (OS dependent)

  Examples:

• "ayy - yank current line into register 'a'

• "ap - paste content from register 'a'

• "+yy - yank current line to system clipboard

• "+p - paste from system clipboard

Search and Replace

Basic Search

• /pattern - search forward for pattern
• ?pattern - search backward for pattern
• n - repeat search in same direction
• N - repeat search in opposite direction

Search Options

• :set ignorecase - case-insensitive search
• :set smartcase - case-sensitive if pattern contains uppercase
• :set incsearch - show incremental search results
• :set hlsearch - highlight all search matches
• :nohlsearch or :noh - turn off highlighting until next search

Search Within Lines

• f{char} - find next occurrence of character on current line
• F{char} - find previous occurrence of character
• t{char} - move till next occurrence of character (cursor before char)
• T{char} - move till previous occurrence of character
• ; - repeat last f, F, t, or T motion
• , - repeat last f, F, t, or T motion in opposite direction

Find and Replace

• :{range}s/{pattern}/{replacement}/{flags} - substitute command

  Common ranges:

• % - entire file

• '<,'> - visual selection (appears automatically when you press : after selecting text)

• {number},{number} - specific line range

• . - current line

• $ - last line

• .,$ - from current line to end of file

  Common flags:

• g - global (replace all occurrences on each line)

• c - confirm each substitution

• i - case insensitive

• I - case sensitive

  Examples:

• :%s/foo/bar/g - replace all occurrences of "foo" with "bar" in the entire file

• :%s/foo/bar/gc - same, but confirm each replacement

• :1,10s/^/#/ - comment out lines 1-10 by adding # at beginning

Advanced Search Patterns

Vim uses regular expressions for powerful pattern matching:

• \<word\> - match whole word
• ^ - beginning of line
• $ - end of line
• . - any single character
• * - zero or more of the preceding character
• \+ - one or more of the preceding character
• \? - zero or one of the preceding character
• \{n,m} - between n and m of the preceding character
• [abc] - any character from the set
• [^abc] - any character not in the set
• \d - digit
• \s - whitespace character
• \S - non-whitespace character

Visual Mode Mastery

Visual Mode Selection

• v - character-wise visual mode
• V - line-wise visual mode
• Ctrl+v - block-wise visual mode (rectangular selection)
• gv - reselect the last visual selection

Visual Mode Operations

Once text is selected, you can:

• d - delete selection
• y - yank (copy) selection
• c - change selection (delete and enter insert mode)
• > - indent right
• < - indent left
• = - auto-indent
• ~ - swap case
• u - make lowercase
• U - make uppercase
• : - perform command on selection (e.g. :s/foo/bar/g)

Block-wise Visual Mode Special Features

With block-wise visual mode (Ctrl+v), you can:

1. Select a rectangular block
2. Press I to insert at the beginning of each line in the block
3. Type your text

4. Press Esc to apply the change to all selected lines

   Similarly:

• A - append to end of each line in block
• c - change the block

• r - replace characters in the block

  This is incredibly powerful for editing columnar data or making the same change across multiple lines at once.

Working with Multiple Files

Buffers

Buffers are in-memory text of opened files:

• :ls or :buffers - list all buffers
• :buffer {number} or :b {number} - switch to buffer by number

• :bdelete {number} or :bd {number} - delete a buffer (close a file)

Windows (Splits)

Windows are viewports onto buffers:

• :split or :sp - horizontal split
• :vsplit or :vs - vertical split
• :new - horizontal split with new file
• :vnew - vertical split with new file
• Ctrl+w s - horizontal split
• Ctrl+w v - vertical split
• Ctrl+w w - cycle through windows
• Ctrl+w h/j/k/l - navigate to left/down/up/right window
• Ctrl+w H/J/K/L - move window to far left/bottom/top/right
• Ctrl+w = - make all windows equal size
• Ctrl+w _ - maximize window height
• Ctrl+w | - maximize window width
• Ctrl+w + - increase window height
