Can a file belong to more than one group?
I was wondering if it were possible to be able to do this.
user = 'bob'
groups = 'trusted'(GID 110) and, 'users' (GID 111)
user = 'tom'
group = 'users' (GID 111)
bob will have r-w-x permission on file 'work' which belongs to GID 110 and 111, because he is a member of GID 110, which has r-w-x permission.
However, tom will only have r-x permission because he is only a member of the 'users' group, and this group only has r-x permisson.
Is it possible to have a file belong to more than one group?
