帮我看看这个问题,
Now   there   are   two   files   named   good.txt   and   bad.txt   in   the   sub-directory   test,   how   can   you   exchange   the   names   of   the   two   files?
(交换两个文件的名字)

------解决方案--------------------
mv good.txt tmp11111111111.txt
mv bad.txt good.txt
mv tmp11111111111.txt bad.txt
