Hi John. Correct me if I am wrong but permission to delete a file depends on the users permissions for the containing directory. If B has write permission on the directory then B can delete the file. However you will likely need to use 'rm -f'. Regards. Jeremy. On Tue, Oct 7, 2008 at 1:54 PM, John Almberg <[EMAIL PROTECTED]> wrote: > The following permissions problem has me stumped: > > 1.
