MPACK(1)                               General Commands Manual                              MPACK(1)



NAME
       mpack - pack a file in MIME format

SYNOPSIS
       mpack  [  -a  ] [ -s subject ] [ -d descriptionfile ] [ -m maxsize ] [ -c content-type ] file
       address ...
       mpack [ -a ] [ -s subject ] [ -d descriptionfile ] [ -m maxsize ] [ -c content-type ] -o out‐
       putfile file
       mpack  [  -a  ]  [  -s subject ] [ -d descriptionfile ] [ -m maxsize ] [ -c content-type ] -n
       newsgroups file

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 con‐
              tents of the subject header.

       -d descriptionfile
              Include the contents of the file descriptionfile in an introductory section at the be‐
              ginning 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, output‐
              file.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 /tmp.

       SPLITSIZE
              Default value of the -m switch.
