Let’s Learn Vim

This post was originally created for https://github.com/therobinkim/lets-learn-vim.



vim is a text editor that is built into many operating systems and henceforth built into terminals. It's rather plain and can be intimidating at first, but can be a lot of fun to learn, and when mastered, significantly improve your ability to edit text.


vim is "an improved version of the vi editor" while emacs and nano are some alternatives. My Macbook Pro runs vim whenever try to run vi, so we’ll focus our discussion on vim.

Use Case

An advanced use case might arise when you’re only able to access a different computer from your terminal (eg, a server located somewhere in the middle of the ocean), and you need to edit some text files on it. With no other “regular” text editor like Sublime Text, Atom, or Visual Studio Code available, you’ll have to use vim or a similar alternative.

A use case you may be more familiar is writing a git commit message when you haven't yet (or can't) associate a non-default text editor with Git. Trying to use vim without a proper introduction can be a psychological barrier and a distraction from what whatever we're trying to do. Fortunately, there are many resources out there (like the document you're reading right now) that can help guide us.


When you enter a vim session, your cursor will be on the first character of the document in normal mode. You can navigate (eg, move your cursor up/down/left/right) and manipulate text (eg, copy/paste). You can usually return to normal mode by pressing ESC.

Insert mode is designed to insert new text. You can enter insert mode from normal mode by pressing i, and return to normal mode by pressing ESC.

Command Mode allows us to enter commands that save the file, quit out of vim, etc. Type : from normal mode (press ESC to get to normal mode), and you'll see a single line at the bottom of your terminal where you can type in commands like:

  • :q to quit*
  • :q! to quit and discard any changes
  • :w to write (aka save) the file
  • :wq to write (aka save) the file and quit

* If you’ve made changes and attempt to exit with :q, vim will alert you with an error that can be avoided with :q! or :wq.

Your First Time

vim is often set as the default editors for many computers. Chances are, you'll accidentally stumble across it when you're prompted to write some text after running git commit.

If you find yourself in vim, I highly recommend typing the following command: :set showmode; when you type :, you will enter command mode at the very bottom of vim:set showmode should be the entirety of the command, so there is no need to press : twice. Double check that your Caps Lock is off as vim is case sensitive!

To get started with writing in what’s essentially a blank text file, press i on your keyboard to enter insert mode, and type out whatever you wanted to. Try using the up, down, left, and right keys to see if you can move your cursor while you're in insert mode. When you're done, push : to enable command mode (see above), type wq to write (aka save) your file and quit, and push enter to submit your command. You did it!
