DESCRIPTIONThe 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.
- 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.
- Encode the named file.
- address ...
- Mail the generated messages to the specified addresses.
- Directory to store temporary files. Default is /var/tmp.
Default value of the -m switch.
