vim 文本编辑器排错

例如：

E325: ATTENTION

Found a swap file by the name "/etc/.my.cnf.swp"

          owned by: root   dated: Fri Jan  9 16:14:10 2015

         file name: /etc/my.cnf

          modified: YES

         user name: root   host name: localhost.localdomain

        process ID: 10223

While opening file "/etc/my.cnf"

             dated: Sun Jan 11 22:57:22 2015

      NEWER than swap file!

(1) Another program may be editing the same file.

    If this is the case, be careful not to end up with two

    different instances of the same file when making changes.

    Quit, or continue with caution.

(2) An edit session for this file crashed.

    If this is the case, use ":recover" or "vim -r /etc/my.cnf"

    to recover the changes (see ":help recovery").

    If you did this already, delete the swap file "/etc/.my.cnf.swp"

    to avoid this message.

Swap file "/etc/.my.cnf.swp" already exists!

问题描述：

这是由于在编辑该文件的时候异常退出了，因为vim在编辑文件时会创建一个交换文件swap file以保证文件的安全性。

解决方案：

每次打开这个文件都会出现这个警告，为了去掉这个警告，需要删除这个swap文件： rm -f /etc/.my.cnf.swap 

这样烦人的警告就消失了。 有时是 删除 rm -f .my.cnf.swap  

查看一下：ls -a 就可以看到.my.cnf.swap 文件
