Learn Vim
Starting Vim
Starting Vim
In this chapter, you will learn different ways to start Vim from the terminal. I was using Vim 8.2 when writing this guide. If you use Neovim or an older version of Vim, you should be mostly fine, but be aware that some commands might not be available.
Installing
I won't go through the detailed instruction how to install Vim in a specific machine. The good news is, most Unix-based computers should come with Vim installed. If not, most distros should have some instructions to install Vim.
For download informations, check out Vim's official download website or Vim's official github repository:
The Vim Command
Now that you have Vim installed, run this from the terminal:
vim
You should see an intro screen. This is the where you will be working on your file. Unlike most text editors and IDEs, Vim is a modal editor. If you want to type "hello", you need to switch to insert mode with i
. Press ihello<Esc>
to insert the text "hello".
Exiting Vim
There are several ways to exit Vim. The most common one is to type:
:quit
You can type :q
for short. That command is a command-line mode command (another one of Vim modes). If you type :
in normal mode, the cursor will move to the bottom of the screen where you can type some commands. You will learn about the command-line mode later in chapter 15. If you are in insert mode, typing :
will literally produce the character ":" on the screen. In this case, you need to switch back to normal mode. Type <Esc>
to switch to normal mode. By the way, you can also return to normal mode from command-line mode by pressing <Esc>
. You will notice that you can "escape" out of several Vim modes back to normal mode by pressing <Esc>
.
Saving A File
To save your changes, type:
:write
You can also type :w
for short. If this is a new file, you need to give it a name before you can save it. Let's name it file.txt
. Run:
:w file.txt
To save and quit, you can combine the :w
and :q
commands:
:wq
To quit without saving any changes, add !
after :q
to force quit:
:q!
There are other ways to exit Vim, but these are the ones you will use daily.
Help
Throughout this guide, I will refer you to various Vim help pages. You can go to the help page by typing :help {some-command}
(:h
for short). You can pass to the :h
command a topic or a command name as an argument. For example, to learn about different ways to quit Vim, type:
:h write-quit
How did I know to search for "write-quit"? I actually didn't. I just typed :h
, then "quit", then <Tab>
. Vim displayed relevant keywords to choose from. If you ever need to look up something ("I wish Vim can do this..."), just type :h
and try some keywords, then <Tab>
.
Opening a File
To open a file (hello1.txt
) on Vim from the terminal, run:
vim hello1.txt
You can also open multiple files at once:
vim hello1.txt hello2.txt hello3.txt
Vim opens hello1.txt
, hello2.txt
, and hello3.txt
in separate buffers. You will learn about buffers in the next chapter.
Arguments
You can pass the vim
terminal command with different flags and options.
To check the current Vim version, run:
vim --version
This tells you the current Vim version and all available features marked with either +
or -
. Some of these features in this guide require certain features to be available. For example, you will explore Vim's command-line history in a later chapter with the :history
command. Your Vim needs to have +cmdline_history
feature for the command to work. There is a good chance that the Vim you just installed have all the necessary features, especially if it is from a popular download source.
Many things you do from the terminal can also be done from inside Vim. To see the version from inside Vim, you can run this:
:version
If you want to open the file hello.txt
and immediately execute a command, you can pass to the vim
command the +{cmd}
option.
In Vim, you can substitute texts with the :s
command (short for :substitute
). If you want to open hello.txt
and substitute all "pancake" with "bagel", run:
vim +%s/pancake/bagel/g hello.txt
The command can be stacked:
vim +%s/pancake/bagel/g +%s/bagel/egg/g +%s/egg/donut/g hello.txt
Vim will replace all instances of "pancake" with "bagel", then replace "bagel" with "egg", then replace "egg" with "donut" (you willl learn substitution in a later chapter).
You can also pass the c
flag followed by the command instead of the +
syntax:
vim -c %s/pancake/bagel/g hello.txtvim -c %s/pancake/bagel/g -c %s/bagel/egg/g -c %s/egg/donut/g hello.txt
Opening Multiple Windows
You can launch Vim on split horizontal and vertical windows with o
and O
, respectively.
To open Vim with two horizontal windows, run:
vim -o2
To open Vim with 5 horizontal windows, run:
vim -o5
To open Vim with 5 horizontal windows and fill up the first two with hello1.txt
and hello2.txt
, run:
vim -o5 hello1.txt hello2.txt
To open Vim with two vertical windows, 5 vertical windows, and 5 vertical windows with 2 files:
vim -Ovim -O5vim -O5 hello1.txt hello2.txt
Suspending
If you need to suspend Vim while in the middle of editing, you can press Ctrl-z
. You can also run either the :stop
or :suspend
command. To return to the suspended Vim, run fg
from the terminal.
Starting Vim The Smart Way
You can pass the vim
command with different options and flags, just like any terminal commands. One of the options is the command-line command (+{cmd}
or -c cmd
). As you learn more commands throughout this guide, see if you can apply it on start. Also being a terminal command, you can combine vim
with many other terminal commands. For example, you can redirect the output of the ls
command to be edited in Vim with ls -l | vim -
.

command.
