What is Vim?

Vim (Vi IMproved) is a highly configurable text editor built for developers and anyone who works with code. Unlike modern editors with menus and buttons, Vim is keyboard-centric, allowing for a faster and more efficient workflow.

Getting Started with Vim

Creating and Editing Files

Create/Edit a file: vim <file-name>
Save and exit: Press Esc, then type :wq and press Enter.
Exit without saving: Press Esc, then type :q! and press Enter.

Vim offers powerful ways to navigate through your text:

Go to the bottom of the file: Shift+G
Go to the top of the file: gg

Searching in Vim

Efficient searching can save you time:

Search forward: /word (then press Enter and use n to find the next match).
Search backward: ?word (then press Enter and use n to find the previous match).
Search for the word under the cursor:
- Forward search: *
- Backward search: #

Replacing Words

Need to replace text? Vim makes it easy:

Replace a word in the entire file: :%s/<old-word>/<new-word>

Undo and Redo

Made a mistake? No problem!

Undo: u
Redo: Ctrl+r

Editing Lines

Vim provides quick ways to insert and modify lines:

Insert a new line below the current line: o
Insert a new line above the current line: Shift+O
Insert at the beginning of the line: Shift+I
Insert at the end of the line: Shift+A

Deleting and Replacing

Editing text in Vim is straightforward:

Delete a single character: Place the cursor on the character and press x.
Replace a single character:
- Press r, then type the new character.
Delete an entire line: dd
Undo all changes: :e!
Delete multiple lines: <number>dd (e.g., 15dd deletes 15 lines).

Copy and Paste

Moving text in Vim is quick and intuitive:

Paste below the cursor: p
Paste above the cursor: Shift+P

Selecting Text

For copy-paste or modifications, you can select text in various ways:

Select part of a line: Press v and use arrow keys.
Select a whole line: Press Shift+V.

Line Numbers

Toggle line numbers for better navigation:

Enable line numbers: :set nu
Disable line numbers: :set nonu

Syntax Highlighting

Make your code readable with syntax highlighting:

Enable syntax highlighting: :syntax on
Disable syntax highlighting: :syntax off

Jump to a Specific Line

Save time by directly jumping to a line:

Go to a specific line: :<line-number> (e.g., :15)

Working with Multiple Files

Want to work on two files at the same time? Here’s how:

Open multiple files: vim -o <file1> <file2>
Switch between files: Press Ctrl+w (twice).
You can copy from one file and paste into the other seamlessly.

Comparing Files

Vim even lets you compare files side by side:

Compare two files: vim -d <file1> <file2>
