My distribution is the latest Gentoo. I have a directory called music which belongs to qdii:commun and which octal access rights are "2070", that is: all permissions are granted to the group (commun), but none to the user (qdii).

Last element: qdii belongs to commun.

qdii@ks396822 ~/commun $ chmod g+wrxs music/
qdii@ks396822 ~/commun $ cd music/
-bash: cd: music/: Permission denied

What’s happening?


qdii@ks396855 ~/commun $ ls -l
total 4
d---rws--- 2 qdii commun 4096 Jun 10 20:26 music
qdii@ks396855 ~/commun $ cd music/
-bash: cd: music/: Permission denied
qdii@ks396855 ~/commun $ groups qdii
wheel commun qdii

The user permissions have higher priority than the group permissions. Otherwise, it would not be possible to create a file that only the owner can access, but the group can not.

Yet, it's confusing : being the owner of that directory here, prevents me from opening it. If it had been owned by anyone else, I would be able to open it. – qdii Jun 10 '12 at 20:31
