Dear c.u.q.-lers,

This caught me by surprise yesterday:

drwx--xr-x 2 root anothergroup 72 2003-02-22 09:19 dir

Because user "pfeiffer" is a member of "anothergroup" he cannot list the
contents of this directory, even though the dir is world-readable (no read
permission).

But if I change the group ownership to my own default group ("users" in this
case), then this works as I would expect (because of the permissions in
other).

Is this difference because my primary group is "users" and therefore my
"ownership" of the file (via my primary group) overrides the restrictive
group setting (which seemingly always overrides the "other" setting)?

With those permissions, members of group anothergroup aren't allowed to read
that directory (--x). Users from other groups are treated as others.

So I learned. Can one then say: group permissions always override others and
owner permissions always override both group and others?

I also see that my supposition (that my primary group is handled differently
than other groups which I am a member of) is wrong. Looks like I wasn't
minding my "whoami"s.

Yes. The most specific matching one takes precedence.

Do group permissions always override permissions for other (both more and less restrictive)?
