Question

我有一个具有完全权限的捆绑目录（777）（包含子目录）

每当我使用cp -r将其复制到另一个目录时，我发现它失去了一些权限。

原因是什么？如何在保持其权限不变的情况下移动此捆绑包？

我有狮子版。

谢谢

使用-p标志：

cp -Rp whatever whereever

来自cp联机帮助页：

Cause cp to preserve the following attributes of each source file
in the copy: modification time, access time, file flags, file mode,
user ID, and group ID, as allowed by permissions.  Access Control
Lists (ACLs) and Extended Attributes (EAs), including resource
forks, will also be preserved.

If the user ID and group ID cannot be preserved, no error message
is displayed and the exit value is not altered.
If the source file has its set-user-ID bit on and the user ID can-
not be preserved, the set-user-ID bit is not preserved in the
copy's permissions.  If the source file has its set-group-ID bit on
and the group ID cannot be preserved, the set-group-ID bit is not
preserved in the copy's permissions.  If the source file has both
its set-user-ID and set-group-ID bits on, and either the user ID or
group ID cannot be preserved, neither the set-user-ID nor set-
group-ID bits are preserved in the copy's permissions.
