⤷Vim Editor

➤ Vim (short for "Vi improved") is a powerful, highly configurable, and efficient text editor used primarily for editing code and text in a terminal or command-line environment.

➤ It's an enhanced/Advanced version of the original Vi editor, which is one of the oldest and most widely used text editors on Linux Systems.

Three Modes of Vim editor:

• Normal mode: Used for navigation and manipulating text (e.g., cut, copy, paste).

• Insert mode: Used for typing and editing text.

• Command-line mode: Used for executing commands like saving, quitting, or searching.

➤ Commands:

• vim file_name → If file is not present it creates a file and opens in vim editor

• i → insert mode

To exit the vim editor

• Type in (esc : wq) → to save and exit

• esc:q! → to quit without saving

• shift+G → to go to last line in a file

• gg → to go to top line in a file

• esc → to come out of modes

• /search word → to search any word in the file

  • followed by n → to go to next word that matches (top to bottom)

  • followed by ? → (bottom to up)

  • followed by * → to search automatically by just pointing cursor to that word

• :%s/word1/replace word→ to replace a word with another word

• u → to undo

• shift+r → to redo

• o → to go to next line in the file

• shift+o → to go up

• shift + i → to go to starting line

• shift + a → to go to last line

• x → to delete a character

• r → replacement mode

• dd → to delete a line

• :e! → to undo everything

• dd & p → to cut and paste

• shift+p → to paste

• shift+v → to select one whole line

• v → visual mode

• y → to copy the selected line

• :set nu → to assign numbers to the lines

  

• :set nonu → to remove numbers

  

• :syntax on/off → to on and off the color scheme

• The syntax is on means the color scheme

  

• Now the syntax is off

• vim -o file1 file2 → two files will open up and down

  

  → Two files one is txt file and second one is script file

• vim -d file1 file2 → to the diff between two files
