This question already has an answer here:
I have an account with secondary group membership in a group that owns a directory. The directory is chmod 760, which should allow writing to the directory, but not listing it. However, this is not allowed. Can somebody explain why?
Rationale: mostly academic; trying to understand permissions in detail. I recognize that I could make the permissions 770 and allow this; I'm not an idiot (at least I don't think so). I just want to understand what write permissions actually mean for a directory, if not file creation.
