在Linux中使用vi命令编辑mysql_backup.sh时遇到下面提示信息

      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 mysql_backup.sh"
    to recover the changes (see ":help recovery").
    If you did this already, delete the swap file ".mysql_backup.sh.swp"
    to avoid this message.

出现这个问题是因为正在编辑mysql_backup.sh时，VPN断开了，等重新连接上去就出现了这个现象。使用ls -a就能在文件当前目录能看到一个名为.mysql_backup.sh.swp的隐藏文件，使用rm .mysql_backup.sh.swp直接删除后即可解决这个问题。
