How to close a tab in vim?

Question

When I use :tabnew myfile in vim it opens a new tab.

When I quit the tab with :q and I move to another tab with :bn , the tab is still there.

Can someone explain why and how to really close it?

Answer 1

You can use :tabclose.

Read more with :help tabpage.

As for the buffer coming back with :bn, I believe this is normal for "hidden buffers", and :bn wraps around to the first buffer when you go past the last one.

See :help buffer-hidden

Answer 2

You're mixing up tabs and buffers. A tab is simply a way of displaying buffers, closing it doesn't do anything to those.

If you want to delete a buffer from the buffer list, use :bd. From the help:

:[N]bd[elete][!]            *:bd* *:bdel* *:bdelete* *E516* :bd[elete][!] [N]         Unload buffer [N] (default: current buffer) and delete it from         the buffer list.  If the buffer was changed, this fails,         unless when [!] is specified, in which case changes are lost.         The file remains unaffected.  Any windows for this buffer are         closed.  If buffer [N] is the current buffer, another buffer         will be displayed instead.  This is the most recent entry in         the jump list that points into a loaded buffer.         Actually, the buffer isn't completely deleted, it is removed         from the buffer list |unlisted-buffer| and option values,         variables and mappings/abbreviations for the buffer are         cleared.
