(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 shell5.sh"
    to recover the changes (see ":help recovery").
    If you did this already, delete the swap file ".shell5.sh.swp"
    to avoid this message.

解决方法：删除当前文件夹下的shell5.sh.swp     即运行   rm .shell5.sh.swp
但是其实在当前文件夹下是找不到shell5.sh.swp的，不知道根本原因是什么 ，只知道执行完之后再vi 就OK了
