--verify-format format-name
      Sets the output format for the --verify command (since dpkg 1.17.2).

      The  only  currently  supported  output  format is rpm, which consists of a line for
      every path that failed any check.  The lines start with 9 characters to report  each
      specific  check  result, a ‘?’ implies the check could not be done (lack of support,
      file permissions, etc), ‘.’ implies the check passed, and an alphanumeric  character
      implies  a specific check failed; the md5sum verification failure (the file contents
      have changed) is denoted with a ‘5’ on the third character.  The line is followed by
      a  space and an attribute character (currently ‘c’ for conffiles), another space and
      the pathname.
