Changing permissions

Question

In the fedora docs they refer to owner and group owner as if both are owners of the file. The leads me to think that any member of a group which tries to change permissions of a file owned by that group will be allowed. Is this right, or can only the "owner" in it's most absolute sense change permissions?

Example

User foo group bar User pc group bar

Can pc change a file creates by foo and group bar

Answer 1

Only the owner (not the group owner) of a file could change its permissions.

The group owner is only used to establish what access permissions have other users of the same group, other than the file owner.

Permissions are not stored on the directory, so you don't need write permissions on the containing directory.
