I am trying to change the group of a file that I (
user123) am an owner of but I am getting an error. It won't let me change the directory permissions, either. It keeps saying the file system is read-only. I don't understand why it won't let me change permissions of a directory of which I am the owner!
(user123) @ subdomain.example.org [/dev/sudo/app/prog/id] $ ls -la total 3 drwxr-sr-x 2 user app 1024 Jun 18 11:12 etc (user123) @ subdomain.example.org [/dev/sudo/app/prog/id] $ chgrp mygroup etc/ chgrp: changing group of `etc/': Read-only file system
