How to Exit Vim – Vim Save and Quit Command Tutorial

I've been using Vim since the first year I started coding. For all the IDEs/editors that I have used, the Vim plugin is e'er the very first plugin that I install.

I know that Vim can be challenging to piece of work in for people who are not familiar with it. In this article, we'll cover some primal topics similar how to exit Vim, rather than quitting Vim.

I will also include the command that yous can utilise to reveal the corresponding assistance documentation. To exercise that, beginning we need to printing ESC a few times, and run the command provided, for example, :h vim-modes, and press Enter.

TL;DR – How to Exit Vim

Press ESC once (sometimes twice)
Make sure you lot are using the English input method
The next step depends on the electric current status and your expectations:
- If you didn't make any changes, type :q and printing Enter/render
- If y'all made some changes and would like to keep them, type :wq and press Enter/return
- If you lot fabricated some changes and would rather discard them, blazon :q! and press Enter/return

If you desire to understand in more than detail how this works, let's dive in.

What are Modes in Vim?

There are seven BASIC modes in Vim and seven additional modes that are considered variants of the Basic modes. Yous may run :h vim-modes inside Vim to read the documentation if you would like to know more.

Fortunately, nosotros don't take to know all of them in order to become started. Merely at that place are three modes that we need to exist aware of: Normal Mode, Insert Style, and Command-line Fashion.

What is normal mode in Vim?

Normal Mode is crucial since information technology's simply in Normal Manner that we can run commands (there are exceptions simply those are beyond the scope of this article).

Say, if we desire to read the documentation of vim-modes, then we accept to outset make sure we are in Normal Way before typing in :h vim-modes. And the most approved manner of entering Normal Style is by pressing ESC. Even if you are already in Normal Mode, pressing ESC will continue you in Normal Mode, and then no worries.

Find it in the Documentation: :h Normal, :h fashion-switching.

What is insert mode in Vim?

Yous utilise Insert Mode to edit the current file (in Vim, this is commonly referred to every bit buffer). By default, we are in the Normal Mode right after we open a file. If we need to brand changes to the current file, first we need to switch to Insert Mode.

The near common manner to make this switch is by pressing i in Normal mode later navigating the cursor to the place that nosotros are going to edit.

In that location are actually many other means to enter Insert Mode as well, similar o, O, a, A, I, and and then on.

Find it in the Documentation: :h Insert, :h i_<Esc>, :h o, :h O, :h a, :h A, :h I.

What is command-line fashion in Vim?

Command-line Mode is normally a "short-lived" mode, which you utilise to run "Ex commands" (not to exist dislocated with the "commands" in Normal Mode).

Fun fact: Vim is actually a contraction of Vi Improved and it is based on another text editor named vi. And six is based on a line editor named ex. Both half dozen and ex were developed by Beak Joy.

Another fun fact for macOS users: in that location is only Vim on macOS and the command 6 is symlinked to vim. Likewise note that the "Ex command" in Command-line Mode is unlike from the "control" in Normal Mode.

You tin enter Command-line Way past typing : in Normal Manner. For instance, if you run the commands above to run across the documentation, you are actually using the Command-line Mode as shortly as you type in :.

Similarly, press ESC if you'd similar to switch back to Normal Mode.

Find it in the Documentation: :h Command-line, :h cmdline-lines.

How to Exit Vim

If you take a look at the documentation of :h quit, annotation that the quit is prefixed with :. This means that quit is used inside Control-line Mode.

In order to enter Command-line Way, first nosotros need to brand certain nosotros are in Normal Mode, then merely type in :. Now that nosotros are in Command-line Mode, simply type in quit and press Enter or return.

Y'all may also discover the :q there, which is actually the autograph version of the :quit control. That being said, we can also quit Vim by executing :q .

It does mention, though, that this control will fail "when changes have been made and Vim refuses to carelessness the current buffer" (if you still think, buffer is but opened file(s), nothing fancy).

In this case, we'd demand to utilize :wq, which ways "write and quit". You tin can find this in the Documentation under :h :wq.

:x is another command that works most the same as :wq. According to :h :x, it is "like :wq, but write only when changes have been made".

The difference hither is that :wq will save the file no matter if yous made changes to it or not. :x won't save the file if you didn't make whatsoever changes. What matters hither is the modification fourth dimension of a file, since :wq will update the modification time but :ten volition not.

At that place are some times that we'd rather not proceed the changes that we've made. At this point, nosotros need the :q! command. The ! is unremarkably referred to equally "blindside", which makes q! something like "force quit".

Do note that if you lot use this way, y'all Volition lose all changes that you have made to this file and there is about no way that y'all can recover them.

How to Troubleshoot Exiting Vim

What if I don't want to enter `Command-line Mode`?

Non a problem. In Normal Mode, y'all can also press ZZ or ZQ to quit Vim. Where ZZ is the same every bit :ten and ZQ is the same equally :q!.

Hither, ZZ and ZQ are considered commands of Normal Mode while :x and :q! are Ex commands.

What if `:wq` failed?

This is legit since :wq could fail when the file is read-only or the file name is missing.

Note that when a file is read-but, Vim won't stop you from opening and editing the file. You lot may also find that :wq! won't work either at that moment. You might cease upwards discarding all changes with :q! and open the same file prefixed with sudo and exercise the aforementioned changes one more than time.

One thing you could practice is to save this file in another directory that you have write permission to, similar ~ or even /tmp. Then move it dorsum to the directory where y'all don't take write permission.

In lodge to accomplish this, you can run :w ~/my-fill-in-file which will save this file under ~. Side by side you lot can utilize the mv command to move this file effectually. Also notation that this is what you need to practise when Vim complains that the file name is missing.

There is another solution correct within Vim. You could run this command: :w !sudo tee %. Here !sudo means to run the sudo command in your shell environs.

For example, :ls will list all buffers in Vim but :!ls will run the ls command from the shell and display the effect. tee copies from standard input (a.k.a. stdin) to standard output (a.thou.a. stdout). % refers to the current filename.

This means that we use the sudo control from the shell environment, copy the content of the current file (note: modified version) from Vim, and redirect the modified content to the file (which is referred to by using the filename).

You will notice the alert above. This warning happens because the file content was updated inside the crush environment without Vim's attention. And then Vim considers this to exist an external modify and lets you know what happened.

You can simply press Enter at this time since you made the external change on purpose.

You may too notice that the modified file content also shows upward above the alert message. This is as expected since it comes from the stdout. If yous don't want to come across it, you may do :w !sudo tee% >/dev/zero, which will discard the stdout from tee.

What if I am lost and take to force-quit?

Well if we try exiting by pressing control + c, Vim volition bear witness us the above info. But you lot may still become around this past Ctrl + Alt + Delete on Windows or Force Quit... on macOS.

Next time when you try to open the same file again, you should encounter this (here I am using a file named foo.txt as an example):

Don't panic – this is as expected, since Vim is trying to aid y'all recover your valuable changes that you lot might have lost.

By checking the directory, yous will find a file with the extension of .swp. This is a swap file (documentation: :h swap-file):

We will see the following if nosotros printing R to recover:

Later pressing Enter, now you'll notice that the changes you fabricated earlier are back. And later on you are done with the recover procedure, y'all can simply remove the .swp file so that you lot won't come across the fault above anymore.

Conclusion

In this article, nosotros covered some fundamentals virtually Vim's modes and how to exit Vim. We also learned how to solve common bug when it comes to exiting Vim.
