vi 编辑器的 rc 文件在哪里。

Question

我想设置系统范围的 vi 设置。

我知道我可以在 /etc/vimrc 和 ~/.vimrc 中为 vim 编辑器设置首选项

但我不认为我在 CentOS7 上的 vi 正在从 vimrc 文件或 /etc/virc 或 ~/.virc 等位置读取任何内容

戳POSIX：

Initialization in ex and vi
   See  Initialization  in  ex  and  vi  for  a  description  of ex and vi
   initialization for the vi utility.

手册页ex说：

   IEEE Std 1003.1-2001  does  not  mention system-wide ex and vi start-up
   files. While they exist in several implementations of ex and  vi,  they
   are  not  present in any implementations considered historical practice
   by IEEE Std 1003.1-2001.  Implementations that have such  files  should
   use  them  only if they are owned by the real user ID or an appropriate
   user (for example, root on UNIX systems) and if they are  not  writable
   by  any  user other than their owner. System-wide start-up files should
   be read before the EXINIT variable, $HOME/.exrc, or local  .exrc  files
   are evaluated.

所以我想/etc/exrc是老派的最佳选择vi。

但是，vi在 CentOS 7 上可能只是vim-minimal，在这种情况下，启动文件仍将使用vim其名称：/etc/vimrc或/etc/vim/vimrc.
