文件/目录权限尾随+(drwxr-xr-x +) [英] file/directory permissions trailing + ( drwxr-xr-x+ )

问题描述

我有一个具有奇怪权限的目录(drwxr-xr-x +)-尾随(+)作为第11个字符，这似乎迫使所有文件和子目录都具有rwxrwxrwx权限，以下是权限.

I have a directory with strange permissions ( drwxr-xr-x+ ) - trailing ( + ) as 11th character, which seems to force all the files and subdirectories to assume rwxrwxrwx permissions, Following is the permissions.

drwxr-x---+  3 root root 4096 Dec 22 15:33 directory

我想摆脱此尾随(+).我已尝试关注.

I want to get rid of this trailing ( + ). I have tried following .

chmod 755 directory/
chmod a-x directory/
chmod u=rwx,g=rw,o=x directory/

我也尝试过以下方法:

sudo chmod u=rwx,g=rx,o-x,u-s,g-s    directory/

任何帮助将不胜感激.谢谢-我被卡住了.

Any help will be appreciated . Thanks - I am stuck .

推荐答案

结尾的 + 表示在目录上设置了 ACL (访问控制列表).

The trailing + signify that ACL, Access Control List, is set on the directory.

您可以使用 getfacl 来获取详细信息

You can use getfacl to get the details

getfacl directory

以下输出来自 getfacl Codespace ，其具有由 setfacl -m u:umesh:rw Codespace 设置的ACL.这里 setfacl 授予用户 umesh 到 Codespace 目录的 rw 权限.

Following output is from getfacl Codespace which have ACL set by setfacl -m u:umesh:rw Codespace. Here setfacl is giving rw permission to Codespace directory for user umesh.

# file: Codespace/
# owner: root
# group: root
user::rwx
user:umesh:rw-
group::r-x
mask::rwx
other::r-x

，例如，对于上述示例，我们可以使用 setfacl 删除 ACL

and we can remove the ACL using setfacl, for example, for the above sample

setfacl -x u:umesh Codespace/

有关 man setfacl 和 man getfacl
