老师，请问为什么不能将文件传送到linux服务器上啊？（老师，极客的这系统也太过分了吧，图片上传了n次显示出错了，没办法只能贴代码咯）

json：

"type": "sftp",

    "save_before_upload": true,

    "upload_on_save": false,

    "sync_down_on_open": false,

    "sync_skip_deletes": false,

    "sync_same_age": true,

    "confirm_downloads": false,

    "confirm_sync": true,

    "confirm_overwrite_newer": false,

    "host": "127.0.0.1",

    "user": "root",

    "password": "0954281879wl",

    //"port": "22",

    "remote_path": "/home/hello/",

shell脚本：

[root@localhost ~]# mkdir /home/hello

mkdir: cannot create directory ‘/home/hello’: File exists

[root@localhost ~]# rm -rf /home/hello

[root@localhost ~]# mkdir /home/hello

[root@localhost ~]# cd /home/hello/

[root@localhost hello]# ll

total 0

文件名显示为0，为什么？
