zh:zh|chgrp chgrp是一条在Unix系统中用于设置文档所归属的组的命令。与chown命令不同，chgrp允许普通用户改变文档所属的组，只要该用户是该组的一员。

调用chgrp的语法为

chgrp 组名 目标1 [目标2 ...]

• "组名"是文档即将关联的组。
• "目标1 [目标2 ...]"是需要改变组的文档或目录的列表。

备注："组名"既可以使用字符名称也可以使用ID。 7

The chgrp (from change group) command may be used by unprivileged users on Unix-like systems to change the group associated with a file system object (such as a file, directory, or link) to one of which they are a member. A file system object has 3 sets of access permissions, one set for the owner, one set for the group and one set for others. Changing the group of an object could be used to change which users can write to a file.
