I want to create a shared folder on my Debian server so that users can create and edit files, but not be able to delete each other's files in that directory.
Users that can read and write files in the map are in a group:
I tried few permission commands like these, but still not succeeding:
setfacl -dm u::rwx,g::rwx,o::r /shared/directory
How can I achieve what I want?
