DESCRIPTION
The mpack program encodes the the named file in one or more MIME mes‐
sages. 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 news‐
groups.
OPTIONS-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 introduc‐
tory 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 environ‐
ment 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 deter‐
mine its type.
-o outputfile
Write the generated message to the file outputfile. If the mes‐
sage has to be split, the partial messages will instead be writ‐
ten 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.
