NAME
mpack - pack a file in MIME format
SYNOPSIS
mpack [ -s subject ] [ -d descriptionfile ] [ -m maxsize ] [
-c content-type ] file address ...
mpack [ -s subject ] [ -d descriptionfile ] [ -m maxsize ] [
-c content-type ] -o outputfile file
mpack [ -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
-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 gen-
erated 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 vari-
able, 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.

MUNPACK(1) USER COMMANDS MUNPACK(1)
NAME
munpack - unpack messages in MIME or split-uuencode format
SYNOPSIS
munpack [ -f ] [ -q ] [ -t ] [ -C directory ] [ filename ...
]
DESCRIPTION
The munpack program reads each RFC-822 message filename and
writes all non-text MIME parts or split-uuencoded files as
files. If no filename argument is given, munpack reads from
standard input.
If the message suggests a file name to use for the imbedded
part, that name is cleaned of potential problem characters
and used for the output file. If the suggested filename
includes subdirectories, they will be created as necessary.
If the message does not suggest a file name, the names
"part01", "part02", etc are used in sequence.
If the imbedded part was preceded with textual information,
that information is also written to a file. The file is
named the same as the imbedded part, with any filename
extension replaced with ".desc".
OPTIONS
-f Force overwriting of existing files. If a message sug-
gests a file name of an existing file, the file will be
overwritten. Without this flag, munpack appends ".1",
".2", etc to find a nonexistent file.
-q Be quiet. Supresses messages about saving partial mes-
sages and about messages with no interesting informa-
tion.
-t Also write the text MIME parts of multipart messages as
files. This option effectively disables the ".desc"
file feature for MIME messages.
-C directory
Change the current directory to directory before read-
ing any files. This is useful when invoking munpack
from a mail or news reader.
ENVIRONMENT
TMPDIR
Directory to store temporary files. Default is /tmp.
FILES
$TMPDIR/message-parts-$USER/
Directory used to store partial messages awaiting
reassembly.
