例：使用vi jetty_stdout.log时 会生成一个 jetty_stdout.log.swp 文件, 然后再开个终端 vi jetty_stdout.log 时会提示：

原因：This is the result of not properly closing an open buffer, usually because of a lost ssh connection. If there were unsaved changes, they can be recovered from this swap file.

=================================================

1、vi是vim的别称，所以直接编译/etc/vimrc即可

1. [admin@inc logs]$ which vi 
2. alias vi='vim' 
3.         /usr/bin/vim
