my .vimrc

:h %<

%<              current file name without extension

我这里的配置是针对vim所设置如果是最原始的vi，那么是不支持下面一些配置的，如：

set mouse=a "enable mouse

set autochdir

出错提示：
E538: No mouse support: mouse=a
E518: Unknown option: autochdir

执行yum install vim后，给vim设置别名vi

[workhard@zl 毕业设计]$ which vi
/bin/vi
[workhard@zl 毕业设计]$ alias vi='vim'
[workhard@zl 毕业设计]$ which vi
alias vi='vim'
