Suppose I have started vim like this:

vim foo bar

Now I decide that I want each of those files in its own tab. Is there a way to do that without exiting vim and adding the -p option to my command line?

  • Many of you are probably looking for tabe % which is mentioned in liuyang1's answer below. Apr 25, 2017 at 13:45

    @MateuszPiotrowski Like I mentioned in this comment to that answer, :tabe % doesn't work with buffers that have no valid filepath. :tab sb works everytime.

You wish to open a buffer in a new tab ?

Split up the screen (Ctrl-W s), take up a window, and Ctrl-W T

  • Hmm. Not quite what I had in mind, but not bad for a start. I didn't know about Ctrl-w T yet. Of course, the first tab will still have two buffers that way.

  • No. After you split the screen into two windows, and open one of them in a new tab, it goes away from the first tab. It won't remain (at least it doesn't on my gvim72). As far as buffers go, they are not connected to windows/tabs ... they are more like memory where vim stores file contents.

  • Ah! You're right. I was misinterpreting the output of :ls.

  • Also, ctrl-w V splits the window vertically. Nov 5, 2009 at 20:33

    CTRL-w v is the correct command for splitting windows vertically

You can accomplish this by combining the tab command with the sb[uffer] command.

First you'll need to know the buffer id of the buffer you wish to open in a new tab. You can find this out with the ls command:

:ls
  1 %a   "foo"                          line 1
  2      "bar"                          line 0

Once you have the id, you can easily open it in a new tab using:

:tab sb 2

The sb command normally opens the given buffer in a new split window, but the tab command causes it to open in a new tab, instead.

The tab command also allows you to specify where in the tab list the new tab should be created. For example, :0tab sb 2 would result in the new ‘bar’ tab appearing at the beginning of the list instead of after the current tab.

    You don’t need the buffer number, give it an unambiguous part of the buffer name and VIM does the rest for you.

    This was so the answer I was looking for and needed. I was dismayed when :tab buffer part-of-name did not open a new tab! But :tab sb part-of-name worked like a charm. Thank you!!!!

When you start vim like that, you don't get a vim client, the text editor is using the terminal or cmd prompt - the two files are in two different buffers. Use :ls to list the buffers:

:ls
  1 %a   "foo"                 line 6
  2      "bar"             line 0

The %a is the active buffer. You can use :b2 to switch to buffer 2 or use :bn to cycle to the next or :bp for previous. I prefer (CTRL-W v) to split windows vertically, rather than (CTRL-W s), which splits horizontally.

If you have 2 files loaded & no tabs (yet), you can, :tabnew and in the new tab type :b2

If you want to always have buffers loaded into their own tabs, check out this article.

  • Yes, but I want to have tabs.

  • So you already have started vim in a way that you have your files in the vim client, not in a cmd / terminal shell? Nov 5, 2009 at 15:57

    I'm not sure what you mean. I use the shell to start vim like described above and then I have a running vim.

  • Ah! I guess I never really understood that buffers aren't local to tabs. I always thought (without thinking really much) that each tab has its own buffer list.

  • On my machine, vim will launch an editor within the shell. To get the vim graphical user interface I have to use gvim. And you are correct - buffers are global to the vim application. Nov 5, 2009 at 17:08

A better way to accomplish what OP asked for is this:

:bufdo tab split

This will open each buffer into a tab of its own, no matter how many there are. If you use this much, it's easy to make into a mapping in your .vimrc. Combined with something like this little vim plugin the following will open every item from :grep (or :Ack) in a tab of its own:

:grep foo
:QuickFixOpenAll
:bufdo tab split

Of course, when resorting to a plugin it would be easy enough to modify it to open the quickfix list contents in directly into tabs.

UPDATE: I've really got to give a shout-out to ggustafsson's comment below. It's far and away the best answer of the lot and beautifully illustrates Vim's tendency towards compositional behavior. The suggestion is:

 :tab sball

It's well worth looking up the Vim help for :tab and :sball to see what's going on here.

  • An similar approach from a previous edit, for posterity, is :bufdo execute "tabnew %". I think the new approach is a bit clearer. May 30, 2012 at 1:37
  • One caveat: if the starting buffer in vim isn't empty, this seems to open the last buffer twice. I'll post an update if I find a simple fix. May 30, 2012 at 1:52

    :tab sball seems to work better. Jan 20, 2013 at 11:07

1. Open two files in Vim.

$ vim foo bar

2. Check the numbers of buffers.

:ls
  1%a "foo"
  2   "bar"

3. Chain two commands: tabnew to open a new tab and b <buffer_number> to load the desired buffer in the tab.

:tabnew | b 2

    The problem with step 3 is that it first creates a new tab with an empty buffer, and then opens buffer 2, resulting in an extra untitled buffer in the buffer list. Better to use :tab sb 2

    @rkjnsn you should post that as an answer - it best answers the question 'how do I edit an existing buffer in a new tab in vim?'

Just add some point which other guys didn't mention.

  • current window to new tab

If have multiple window, <C-W>T will move this window to new tab. However, this shortcut only for "Window", not "buffer". If prefer this style, :sp or <C-W>s to duplicate current buffer to one more window, then <C-W>T to move it to new tab.

4 keystrokes or 7 keystrokes.

  • current buffer to new tab

:tabe % to open new tab for current buffer.

7 keystrokes.

  • buffer to new tab

If use CtrlP plugin, also could use "CtrlPBuffer", then with <C-t> shortcut to open it with new tab page. This style, easily to switch to different buffers.

With shortcut of "CtrlPBuffer", 4 keystrokes or more.

  • :tabe % is what I've been looking for for a long time, thanks!

  • No, :tabe % doesn't really open a new tab for current buffer. What happens is that % gets expanded to the filepath of the current buffer and :tabe opens that path. Vim will see you're trying to open a file you already have open and will reuse the buffer you have. This means that this doesn't work with buffers that have no filepath. If you open up a new file with :new and you haven't saved it, you can't put it on a new tab with this. The real command you need is what rkjnsn put in their answer: :tab sb % or shorter: :tab sb

If you are using fzf.vim plugin. You could list the buffers using :Buffers, then select the specific buffer with <C-j/k> (or filter by typing buffer number or file name), then use <C-t> to open the selected buffer in new tab.

I use below mapping to quickly list the buffers:

nnoremap <leader>b :Buffers<CR>
