DESCRIPTION

       The  mpack  program  encodes the the named file in one or more MIME messages.  The resulting messages are
       mailed to one or more recipients, written to a named file or  set  of  files,  or  posted  to  a  set  of
       newsgroups.

OPTIONS

       -a     Set the Content-Disposition to attachment.  If -a is not used the Content-Disposition is inline.

       -s subject
              Set  the  Subject  header field to Subject.  By default, mpack will prompt for the contents of the
              subject header.

       -d descriptionfile
              Include the contents of the file descriptionfile in an introductory section at  the  beginning  of
              the first generated message.

       -m maxsize
              Split  the  message  (if  necessary) into partial messages, each not exceeding maxsize characters.
              The default limit is the value  of  the  SPLITSIZE  environment  variable,  or  no  limit  if  the
              environment  variable  does  not  exist.  Specifying a maxsize of 0 means there is no limit to the
              size of the generated message.

       -c content-type
              Label the included file  as  being  of  MIME  type  content-type,  which  must  be  a  subtype  of
              application,  audio,  image,  or  video.   If this switch is not given, mpack examines the file to
              determine its type.

       -o outputfile
              Write the generated message to the file outputfile.  If the message has to be split,  the  partial
              messages will instead be written to the files outputfile.01, outputfile.02, etc.

       -n newsgroups
              Post the generated message(s) to the comma-separated netnews newsgroups.

       file   Encode the named file.

       address ...
              Mail the generated messages to the specified addresses.

ENVIRONMENT

       TMPDIR Directory to store temporary files.  Default is /var/tmp.

       SPLITSIZE
              Default value of the -m switch.

                                                                                                        MPACK(1)
