Como faço para recuperar um arquivo com o vim?

Question

Estou tentando recuperar meu arquivo sudoers. Digitei meu terminal do Chrome OS

vim -r /etc/sudoers

Depois disso, ele me deu o seguinte,

Swap files found:
    Using specified name:
1.    .sudoers.swm
          owned by root    dated: Tue Sep 29 22:45:22 2015
          [cannot be opened]
2.    .sudoers.swn 
          owned by: root   dated: Tue Sep 29 15:39:12 2015
          [cannot be opened] 
3.    .sudoers.swo

         process ID: 17058 (still running)
6.    sudoers.swp

      -- none --
