I can answer this question.  All major file compressors except 7-zip
have such an option.

man bzip2:

   -q --quiet

          Suppress non-essential warning messages.  Messages pertaining
          to I/O errors and other critical events will not be suppressed.

man gzip:

   -q --quiet
          Suppress all warnings.

man unzip:

   -q perform operations quietly (-qq = even quieter).  Ordinarily unzip
      prints the names of the files it’s extracting or testing, the
      extraction methods, any file or zipfile comments that may be
      stored in the archive, and possibly a summary when finished with
      each archive.  The -q[q] options suppress the printing of some or
      all of these messages.

man unrar:

   -inul  Disable all messages.

(the latter switch name is quite ugly)

There are many ignored requests to add such option to 7-zip:


If you want add a new request, please ask for -q --quiet at sourceforge.
