我們用到的比較多的可能是Limit的使用，Limit大致有以下動作，基本能覆蓋全部的權限了，大家靈活使用就是了。

CMD：Change Working Directory 改變目錄
MKD：MaKe Directory 建立目錄的權限
RNFR： ReName FRom 更改目錄名的權限
DELE：DELEte 刪除文件的權限
RMD：ReMove Directory 刪除目錄的權限
RETR：RETRieve 從服務端下載到客戶端的權限
STOR：STORe 從客戶端上傳到服務端的權限
READ：可讀的權限，不包括列目錄的權限，相當于RETR，STAT等
WRITE：寫文件或者目錄的權限，包括MKD和RMD
DIRS：是否允許列目錄，相當于LIST，NLST等權限，還是比較實用的
ALL：所有權限
LOGIN：是否允許登陸的權限

針對上面這個Limit所應用的對象，又包括以下范圍

AllowUser 針對某個用戶允許的Limit
DenyUser 針對某個用戶禁止的Limit
AllowGroup 針對某個用戶組允許的Limit
DenyGroup 針對某個用戶組禁止的Limit
AllowAll 針對所有用戶組允許的Limit
DenyAll 針對所有用戶禁止的Limit
