Here, let's assume every item was created by its owner. rw-r-r- user2:ourgroup |- group_dir/user2_submission/README consider the following setup: drwxrws- root:ourgroup |- group_dir/ĭrwxr-sr-x user1:ourgroup |- group_dir/user1_submission/ĭrwxr-sr-x user2:ourgroup |- group_dir/user2_submission/ Only people in the ourgroup group can access group_dir.The group controlling the access to the group_dir directory is ourgroup.Actually, the directory -x execution bit could be just what you need. However, this does not require you to restrict the permissions in the whole directory structure. So, basically, from what I see, you want to control the access to a directory using the groups mechanism. In your case however, there might be another solution. However, while this can be configured on FreeBSD, other UNIX & Linux systems just ignore u+s. Setting a default owner "automatically" would require a directory setuid behaving like setgid. If there is a better way than what I’m attempting, I’m all ears. Anything created in this directory inherits the permission scheme from its parent. What I want is to have a directory that can be shared by adding a group to a user. I haven't been able to figure out if ACL can help me with forced ownership.
I found an example using INotify but that strikes me as high-maintenance, since it requires scripting.
I expect I could periodically surf through the entire directory with a cron-job, but that strikes me as inefficient for what is essentially a once-pr-file command. As such, even if i should remove that user from the access group, I would not remove his access completely.Īre there other options I missed for ensuring that all files and sub-directories have the same owner? My problem is that the owner of the file or directory is still the user that created it. The files will be fairly small, I don’t anticipate anything bigger than 50MB. The directory will contain a tree structure with directories and files, with the total amount of files likely being a few million. Access to this directory and anything underneath, will be controlled by the directory's group, which will be added to the users in question.Īs such I created the folder "sticky group" chmod g+s set. I have a directory that contains data shared between a number of users.
