Since the 1970s, Vi and Vim are popular amongst developers and are present on most UNIX-based servers.
These free and open source modal text editors can be a bit hard to use at first, but they are extremely powerful.
Here is our ultimate Vim Cheat Sheet, featuring over 150 commands to supercharge your coding with Vi/Vim.
A Quick Intro to Vim
Vi is a modal text editor first released in 1976 for Unix systems. Vim, (Vi Improved) Vi’s successor, was first released in 1991. Despite its very old age, Vim is extremely popular among web developers and system administrators, as it is installed by default on all Unix-based systems (Mac OS and Linux distros).Unlike classic text editors, Vim features different modes used for different operations. Vim has a total of 12 modes, although you will mostly use the following:
- Insert Mode: This mode is used to insert text by typing, like you would do on any other text editor. To enter insert mode, type
i
while in command mode. - Command Mode: Also named Normal Mode, this mode is used to type Vim commands such as those you’ll find in our Vim Cheat Sheet. To exit insert mode and enter command mode, hit the
Esc
key of your keyboard. - Visual Mode: Similar to command mode, but used to highlight areas of text. Normal commands are run on the highlighted area, which, for instance, can be used to move or edit a selection. Press the
v
key to start visual mode. To exit visual mode, press theEsc
key.
Basics
Let’s start with basic commands that will allow you to write, save and quit files. Remember that these Vim commands need to be typed while in command or visual mode. Exit insert mode by hitting the Esc key, then type the command of your choice.
:e filename | Open filename for edition |
:w | Save file |
:q | Exit Vim |
:q! | Quit without saving current file |
😡 | Write/Save file (if changes has been made) and exit |
:sav filename | Save current file as filename |
. | Repeat the last change made in normal mode |
5. | Repeat 5 times the last change made in normal mode |
Moving In The File
Vim features powerful commands that allow you to easily move the cursor position to any desired location within the current file, making it quick and easy to insert text.
