Can I allow users to chmod a file not owned by them?

August 6, 2022 by Magenaut

I would like to allow users to chmod a file that is owned by root or some user that is not themselves. I have chmod’ed the file to 777 and I get “operation not permitted”. I have added the user to the group of the file and get the same. Why can’t a user chmod a file they have write access to?

permissions 755 on /home//

August 6, 2022 by Magenaut

I am wondering why by default my directory /home/<user>/ has permissions set to 755. This allows other users to enter into directories and read files in my home. Is there any legitimate reason for this ?
