I am trying to execute chown
on a directory that has the following permissions and owners:
drwxrwxr-x 2 justin devs 4096 Jan 1 20:42 test
I am trying to simply execute the following as the justin
user:
chown justin:nginx test
So basically just change the group owner to nginx
, but I am getting:
chown: changing ownership of `test/': Operation not permitted
Any ideas?

First, use the
chgrp
command instead ofchown
and that will work.In the case of using
chown
, for security reasons in most Linux contexts, any ownership change is restricted to the root user even though you are marked as the owner of the file, directory, etc or not. In one case, this is to prevent users from evading quotas by setting the file permission bits to 777 and changing the ownership of a file to some other unknown user and eating up their quota.So using the
chown
command in a user context, especially where the ownership is not changing should not be used just to change the group of a file.NOTE: You must be a member of the group you are attempting to change the file to. This can be verified by
id -a
. If you are not in the group, you will get this message eventhough you are the owner of the file.
