如果把file文件里上级目录相同的只保留最新的一行，比如
drwxr-xr-x 2 root root 32768 2018-04-17 15:34:54 /data/fastdfs/storage/store/path0/data/05/EB
drwxr-xr-x 2 root root 32768 2018-04-17 19:21:03 /data/fastdfs/storage/store/path0/data/05/EE

只保留后面一行
drwxr-xr-x 2 root root 32768 2018-04-17 19:21:03 /data/fastdfs/storage/store/path0/data/05/EE
file文件如下
