For the file, each corresponding permission allows following actions. • The read (r) permission allows owner to examine contents of the file. • The write (w) permission allows owner to modify the file file. • The execute (x) permission allows owner to run the file as a command. For the directory, each corresponding permission allows following actions. • The read (r) permission allows owner to list contents The write (w) permission allows owner to add or remove files in the directory. • The execute (x) permission allows owner to access files in the directory. Here, the execute permission on a directory

for user g stands for group o stands for others Then you type either + or - to add a permission, or to remove it. Then you enter one or more permissions symbols ( r , w , x ). All followed maximum of 7, and it's calculated in this way: 1 if has execution permission 2 if has write permission 4 if has read permission This gives us 4 combinations: 0 no permissions 1 can execute permissions on files. 68 Other users belonging to the same group ( g ) have read and execution permission, same as all the other users ( o ). In the numeric notation, we typically change the last 3

ACL_USER_OBJ：相当于Linux里file_owner的permission 2. ACL_USER：定义了额外的用户可以对此文件拥有的permission 3. ACL_GROUP_OBJ：相当于Linux里group的permission 4. ACL_G ACL_GROUP：定义了额外的组可以对此文件拥有的permission 5. ACL_MASK：定义了ACL_USER, ACL_GROUP_OBJ和ACL_GROUP的最大权限 (这个我下面还会专门讨论) 6. ACL_OTHER：相当于Linux里other的permission setfacl 设置文件访问控制列表 - 1029 - 本文档使用 书栈网 · BookStack.CN 构建

where possible. The option to rename is grayed out If Rename is grayed out, you do not have permission to rename the file. You should use caution with renaming such files, as renaming some protected system.
