delete permission for deleting for all users/gorups

Question

I have a basic question about file permission on Linux.

I would like to have my file to be deletable by all users/all groups on a machine.

At the moment I have a specific user user_A that creates a file with permission 0666, but if another user user_B tries to delete that file Linux doesn't allow that and says no permisison.

Which numeric value should I use?

Answer 1

In traditional Unix/Linux permissions, give that user write access to the directory containing the file. A person can delete any file in a directory to which they have write access.

To grant everybody permission to delete any file in a directory (and also to create files there)

chmod o+w directoryname

For finer grained controls use ACLs as described by RedHat, Ubuntu and others.
