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

DESCRIPTION

The mpack(1) program encodes the named file in one or more Multipurpose Internet Mail Extensions (MIME) messages. The resulting messages are mailed to one or more recipients (specified by address), written to a named file or set of files, or posted to a set of newsgroups.

The mpack(1) command takes the following options:

-s subject

Set the Subject header field to Subject. By default, mpack(1) 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(1) 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, and so on.

-n newsgroups

Post the one or more generated messages to the comma-separated netnews newsgroups.

ENVIRONMENT VARIABLES

The mpack(1) utility makes use of the following environment variables, if set:

TMPDIR

Directory to store temporary files. Default is the value of

getconf CS_TMPDIR

which is normally /tmp.

SPLITSIZE

Default value of the -m switch.
