assign multiple groups to a folder :(

[iinfi]

hi all

is it possible to assign multiple groups to a folder?

eg i have a folder /shared
i want the folder to be accessible by users from groups g1,g2,g3.

i can add a user to multiple groups but cannot assign a file/folder to multiple groups.

i don't think its possible, just make a group that has members of those 3 groups, and make the group owner of that directory/file that new group

If the filesystem supports ACL's and is mounted with ACL support, you can add any combination of user/group access on files/dir's.

ACL Example

Not possible, unless you use ACLs (a real pain) or do as they suggested, having a group with people from multiple groups, which is even a bigger pain.
I'm still trying to find a way to manage that, and haven't found anything that will compare to the ACLs in Windows.
There is no true inheritance of permissions either (no, -R is not "inheritance").
