Renaming a file does not change the file itself. It updates the directory. Any user in group wheel has the authority to write to the directory (e.g., change a file's name). The directory permissions are rwx for group wheel. You can either try a user on machine B who is not in group wheel or change the directory permissions to 755 on /usr/foo/bar. Then it would work as you expect. _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
