我们用到的比较多的可能是Limit的使用，Limit大致有以下动作，基本能覆盖全部的权限了，大家灵活使用就是了。

CMD：Change Working Directory 改变目录
MKD：MaKe Directory 建立目录的权限
RNFR： ReName FRom 更改目录名的权限
DELE：DELEte 删除文件的权限
RMD：ReMove Directory 删除目录的权限
RETR：RETRieve 从服务端下载到客户端的权限
STOR：STORe 从客户端上传到服务端的权限
READ：可读的权限，不包括列目录的权限，相当于RETR，STAT等
WRITE：写文件或者目录的权限，包括MKD和RMD
DIRS：是否允许列目录，相当于LIST，NLST等权限，还是比较实用的
ALL：所有权限
LOGIN：是否允许登陆的权限

针对上面这个Limit所应用的对象，又包括以下范围

AllowUser 针对某个用户允许的Limit
DenyUser 针对某个用户禁止的Limit
AllowGroup 针对某个用户组允许的Limit
DenyGroup 针对某个用户组禁止的Limit
AllowAll 针对所有用户组允许的Limit
DenyAll 针对所有用户禁止的Limit
