I'm working in Ubuntu 3.13.The permissions on a drive are such that the owner can see directories and files with these permissions:drwxrwxr-x    2 michael atlas    4096 Feb 15 12:34 temp2drwxrwxr-x    2 michael atlas   12288 Mar 18 16:14 temp3while another member (ubuntu) of the group 'atlas' sees this:d????????? ? ? ? ?            ? temp2d????????? ? ? ? ?            ? temp3unless ubuntu uses sudo ls -l, then the owner, group, and permissions look the same as when michael does an ls -l.Here it can be seen the two users are in the same group:ubuntu@lincloud:~$ grep '^atlas' /etc/groupatlas:x:1001:ubuntu,michaelWhat is the cause of the problem? How do I fix it?
User cannot see directory permissions
permissions;directory;ls
The parent directory of temp2 and temp3 is where the issue lies. Your atlas group has read permissions on the parent directory and you need read AND execute in order to see the files and their permissions.if you're in the directory with temp2 and temp3 you can fix the issue with the following command: sudo chmod g+x .
