Vim: Close All Buffers But This One

Question

How can I close all buffers in Vim except the one I am currently editing?

Answer 1

Closing all open buffers:

silent! execute "1,".bufnr("$")."bd"

Closing all open buffers except for the current one:

function! CloseAllBuffersButCurrent()
  let curr = bufnr("%")
  let last = bufnr("$")

  if curr > 1    | silent! execute "1,".(curr-1)."bd"     | endif
  if curr < last | silent! execute (curr+1).",".last."bd" | endif
endfunction

Add this function to .vimrc and call it using :call CloseAllBuffersButCurrent().

Convenience map:

nmap <Leader>\c :call CloseAllBuffersButCurrent()<CR>
