file
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.
-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.
TMPDIR
Directory to store temporary files. Default is /usr/tmp.
SPLITSIZE
Default value of the -m switch.
