在 Unix/Linux 系统上沿用了多年的权限机制,由于欠缺灵活性,在现今的信息系统上显
得落后和不敷应用。然而一个新的权限机制标准已经诞生出来,本文将会为大家介绍这个新
机制在 Linux 上的操作方式。
传统上,在 Linux 系统中每个档案和目录都设有权限 (permission) 来决定那些人能
够使用这个档案。
权限分为三组,分别为:拥有者 (file owner),群组 (group),及其它 (other)。
每组中再设有其属性。属性亦分为三种,分别为:读取 (read),写入 (write),及执行
(executable)。
我们可以用 "ls -l" 来检视档案的权限:
-rwxrw-r– 1 adam mis 272401 May 10 2003 report.doc
