The following output is from the "ll" command:

drwx------ 2 you other 96 Mar 2 19:51 data

From this information "data" is a:

A. deleted file waiting for trash collection.

B. file, currently in use by two users.

C. private directory.

D. public directory.

C. The "d" at the front of the line denotes a file of type "directory".
答案是D，但我感觉为什么说是 private directory呢，是不是没有这个概念,因为这个目录只有属主才有所有权限，别的用户没有任何权限
