What was your actual command when deleting the file(s)? If no filename globbing pattern was used, then I think the shell can be ruled out as the culprit. If a globbing pattern was used, e.g. .*DS_Store .DS_Store $ touch .DS_Store ._.DS_Store $ ls -la total 8 drwx------ 2 kk wheel 512 May 28 16:41 . drwxrwxrwt 7 root wheel 512 May 28 16:41 .. -rw-r--r-- 1 kk wheel 0 May 28 16:41 .DS_Store -rw-r--r-- 1 kk wheel 0 May 28 16:41 ._.DS_Store $ rm .DS_Store $ ls -la total 8 drwx------ 2 kk wheel 512 May 28 16:41 . drwxrwxrwt 7 root wheel 512 May 28 16:41 .. -rw-r--r-- 1 kk wheel 0 May 28 16:41 ._.DS_Store Note that bash, the shell, would not warn you about deleting files. This may possibly be something that rm does if used with its -i option, or under some other circumstances having to do with the permissions on the files. -- Kusalananda Sweden
