There is another user 'userbi'. When I try to delete files in directory source with user userbi, I get permission denied. How could I assign 'delete file' privileges to user userbi in source directory?
Yes, userbi is the group and the userbi user is member of this group userbi. My question is that how can I assign delete privileges over the source directory to user userbi?
Check that the files in the directory have "group" write permission. So in the target directory and as the owner of the files or as root run the following command.
chmod g+w *
Also ensure that "userbi" has permission to make changes under /u01/source
