什么可以覆盖 Linux 目录的组权限？
我以 user1 身份登录，grp1 是我的辅助组之一。那么为什么我无法访问 grp1 具有读取权限的文件夹呢？
[user1@machine ~]$ groups user1
user1 : user1 users grp1
[user1@machine ~]$ sudo ls -ld /etc/httpd/logs
drwxr-x--- 4 root grp1 4096 Sep 11 03:59 /etc/httpd/logs
[user1@machine ~]$ ls /etc/httpd/logs
ls: /etc/httpd/logs: Permission denied
I am logged in as user1, and grp1 is one of my secondary groups. So why would I not be able to access a folder on which grp1 has read permissions?
[user1@machine ~]$ groups user1
user1 : user1 users grp1
[user1@machine ~]$ sudo ls -ld /etc/httpd/logs
drwxr-x--- 4 root grp1 4096 Sep 11 03:59 /etc/httpd/logs
[user1@machine ~]$ ls /etc/httpd/logs
ls: /etc/httpd/logs: Permission denied

通过运行
id检查您当前是否在该组中 - 如果您在添加该组成员身份后尚未登录（或 su'ed），则您将无法还没有。Check whether you are currently in that group by running
id- if you haven't logged in (or su'ed) since adding that group membership, you won't have it yet.请检查您是否有父目录的读取权限
Please check if you have read permission to parent DIR
您可以在写入与 grp1 共享的文件之前设置组：
新grp grp1
You can set the group before writing a file shared with grp1:
newgrp grp1
