I'm trying to create a shared folder on my root partition that anyone in a particular group can read and write to and any new files within that folder are also read writeable by anyone in that group no matter what. I've managed to create a folder whereby new users can write to it - but any new files are read only to the group.

Steps I've taken:

mkdir /storage
chown -R root:storage-public /storage
chmod -R 2775 /storage
touch test.txt

But these are the permissions I'm getting from my test file:

-rw-r--r-- 1 root storage-public 13 Oct 12 21:59 test.txt

Can anyone help?

Also worth mentioning that I've tried doing this under ACLs but it seems that the posix permissions override the ACL and I get an effective line next to the output of getfacl.

  • didn't you want to touch /storage/test.txt && ls -la /storage/test.txt?

  • What's the umask set to?

  • @dusan.bajic - yeah but I'm already in the directory so it's not necessary to specify the path. Umask is set to 0002

You have the setgid flag on, which is supposed to have group permissions inherited. However this only applies if the person creating the file is in that group.

Since you created the file test.txt are you are of the storage-public group?
