/usr/include/zconf.h属性变为----------

Question

运行yum update /usr/include/zconf.h后变为

    ---------- 1 root root 9544 May  6 16:43 /usr/include/zconf.h
    chmod 0766 /usr/include/zconf.h
    chmod: changing permissions of `/usr/include/zconf.h': Permission denied

即使在root下也无法更改属性。如何更改属性？

请帮忙。 感谢

以下内容应修正权限：

SELECT table1.name , table1.age FROM table1 ORDER BY table1.age 
union all
SELECT table2.name , table2.age FROM table2 ORDER BY table2.age
union all
SELECT table3.name , table3.age FROM table3 ORDER BY table3.age 

您需要sudo su - # enter root password... chmod 755 /usr /usr/include chmod 644 /usr/include/zconf.h 对文件父目录的权限：

• wx - 阅读目录内容
• x - 修改目录中的文件
