How to Use Vim Editor in Linux: Basic Commands and Tips

To use the vim editor in Linux, open a terminal and type vim filename to edit or create a file. Use i to enter insert mode for typing, Esc to return to command mode, and :wq to save and exit.

Syntax

The basic syntax to open or create a file with Vim is:

• vim filename: Opens the file named filename or creates it if it doesn't exist.
• Inside Vim, you switch between modes: command mode and insert mode.
• Use i to enter insert mode to type text.
• Press Esc to return to command mode to run commands.
• To save and exit, type :wq in command mode and press Enter.

bash

vim filename

Example

This example shows how to create a file, add text, save, and exit Vim.

bash

vim example.txt

# Inside Vim:
# 1. Press i to enter insert mode.
# 2. Type: Hello, Vim!
# 3. Press <Esc> to return to command mode.
# 4. Type :wq and press Enter to save and exit.

Output

File 'example.txt' is created with the text 'Hello, Vim!'

Common Pitfalls

Beginners often get stuck because Vim starts in command mode, so typing letters won't insert text until you press i to enter insert mode.

Another common mistake is trying to exit Vim with Ctrl+C or Ctrl+Z, which does not save changes.

Always press Esc to enter command mode, then use :wq to save and quit, or :q! to quit without saving.

bash

Wrong way:
# Type text immediately after opening Vim (no insert mode)

Right way:
# Press i to enter insert mode before typing
# Press Esc to go back to command mode
# Use :wq to save and exit

Quick Reference

Command	Description
vim filename	Open or create a file named filename
i	Enter insert mode to type text
Esc	Return to command mode
:w	Save changes without exiting
:wq	Save changes and exit Vim
:q!	Exit Vim without saving changes
u	Undo last change
/text	Search for 'text' in the file

Key Takeaways

Open files with 'vim filename' and switch between insert and command modes.

Press 'i' to start typing and 'Esc' to stop typing and run commands.

Save and exit with ':wq' and quit without saving with ':q!'.

Remember Vim starts in command mode, so you must enter insert mode to type.
