-0digits
          specifies the record separator ($/) as an octal number.
          If  there  are  no  digits,  the  null character is the
          separator.  Other switches may precede  or  follow  the
          digits.   For  example,  if  you have a version of find
          which can print filenames terminated by the null  char-
          acter, you can say this:

              find . -name '*.bak' -print0 | perl -n0e unlink

          The special value 00 will cause Perl to slurp files  in
          paragraph  mode.   The  value  0777  will cause Perl to
          slurp files whole since there  is  no  legal  character
          with that value.
