除了特定的用户所有者,每个文件和目录还具有一个组所有者。
In addition to a specific user owner, every file and directory also has a group owner.
例如,只有在源和目标计算机对相同用户使用相同id的情况下,才能保留文件所有者和组所有者设置。
For example, the file ownership and group ownership Settings can only be preserved if the source and destination machines use the same IDs for the same user.
这些属性包括文件所有者及组权限,访问控制列表(acl),以及扩展文件属性。
These attributes include file owner and group permissions, access-control lists (ACLs), and extended file attributes.
