Linux 权限组与其他权限组

Question

Let's suppose that for a certain file the permissions look like this:

rw----r--

Does this mean that everyone except for the group members have read access to the file, or that r which appears for others overrides the group - and gives read access to the group members as well?

Is there any difference for directories?

Answer 1

Yes, that will grant read permission to everyone but the members of the group. It doesn't matter if it's a directory or not. ACLs would probably be better in a situation where one would like to do that.
