1. Basic Usage: To use the vi command, open a terminal and type “vi” followed by the name of the file you wish to edit. For example, to edit a file named “test.txt”, you would type “vi test.txt” and press Enter. Vi opens the file in its editing mode.

2. Modes in vi: Vi has two primary modes – command mode and insert mode. In the command mode, you can navigate through the document, move the cursor, and issue various commands. To enter insert mode and start writing or modifying text, press the “i” key. You can return to the command mode by pressing the Escape key.

3. Editing Text: In vi, you can navigate through the document using navigation keys like arrow keys or “h”, “j”, “k”, and “l” keys for left, down, up, and right respectively. To delete characters, use the “x” key. To delete a line, press “dd”. To save the changes and exit vi, press “:” to enter command mode and type “wq” (write and quit).

4. Advanced Features: Vi has numerous advanced features for editing text, such as copy/paste, search/replace, and undo/redo. To copy a line, press “yy” in command mode. To paste, move the cursor to the desired location and press “p”. To search for a specific word, press “/” in command mode followed by the word. To replace a word, use the “:” command followed by “s/old_word/new_word/g” (old_word is the word to be replaced and new_word is the replacement).

5. Customization: Vi allows users to customize its behavior by modifying the configuration file called “.vimrc”. This file contains settings and customization options to enhance the editing experience. Users can change settings such as the default indentation, file types, color schemes, and key mappings.
