How do I close all open tabs at once?

Question

Shortest/simplest/fastest way would be:

:qa

To save work in all tabs and quit:

:wqa

I often use :tabo (:tabonly) to close all other tabs.

That can be done with the following command (in normal or escape mode):

:tabdo :q

"tabdo" apparently executes the command for all the open tabs.

Adding to what fuentesjr said:

:qa!

Will force quit all tabs, if you don't care about saving.

You can use any of these Vim Ex commands to Exit Multiple Windows And Buffers:

1. :qa :qall

   Exit Vim, unless there are some buffers which have been changed. (Use :bmod to go to the next modified buffer). When 'autowriteall' is set all changed buffers will be written, like :wqall.

2. :conf qa :confirm qall

   Exit Vim. Bring up a prompt when some buffers have been changed. See :confirm.

3. :qa! :qall!

   Exit Vim. Any changes to buffers are lost. Also see :cquit, it does the same but exits with a non-zero value.

4. :quita :quitall :quita! :quitall!

   Same as :qall.

5. :wqa :wqall :xa :xall

   Write all changed buffers and exit Vim. If there are buffers without a file name, which are readonly or which cannot be written for another reason, Vim will not quit.

6. :conf wqa :confirm wqall :conf xa :confirm xall

   Write all changed buffers and exit Vim. Bring up a prompt when some buffers are readonly or cannot be written for another reason. See :confirm.

7. :wqa! :xa! :wqall! :xall!

   Write all changed buffers, even the ones that are readonly, and exit Vim. If there are buffers without a file name or which cannot be written for another reason, Vim will not quit.

To read about these in Vim, type the following Ex command

:help window-exit

:qall

This closes all tabs and open buffers.
