How to set delete permissions for other Linux users?

Question

linux

There are 3 users in the system: root, tom, fluff. Having created the file on behalf of the volume, what rights should I give it so that the fluff user can delete it. Tom and fluff are in group 1. Tried chmod a+rw (didn't help).

Answer 1

The right to delete a file is given to a directory, not to the file itself, because by deleting a file you are "editing" the directory.
Having the right to write to a file, you can "nullify" it by writing nothing to it, but not deleting it.
