MHLIST(1mh)

NAME
mhlist - list information about MIME messages

SYNOPSIS

mhlist [+folder] [msgs] [-file file] [-part number] ... [-type content] ... [-verbose | -noverbose] [-Version] [-help]

DESCRIPTION
The mhlist command allows you to list information (essentially a table of contents) about the various parts of a collection of MIME (multi-media) messages.

mhlist manipulates MIME (multi-media messages) as specified in RFC-2045 thru RFC-2049 (See mhbuild(1)).

A one-line banner is displayed above the listing. The size of the `native' (decoded) format of each content is evaluated. This provides an accurate count at the expense of a small delay. If the -verbose switch is present, then the listing will show any `extra' information that is present in the message, such as comments in the `Content-Type' header.

The option -file file directs mhlist to use the specified file as the source message, rather than a message from a folder. If you specify this file as `-', then mhlist will accept the source message on the standard input. Note that the file, or input from standard input should be a validly formatted message, just like any other mh message. It should NOT be in mail drop format (to convert a file in mail drop format to a folder of mh messages, see inc(1)).

By default, mhlist will list information about the entire message (all of its parts). By using the -part and -type switches, you may limit the scope of this command to particular subparts (of a multipart content) and/or particular content types.

A part specification consists of a series of numbers separated by dots. For example, in a multipart content containing three parts, these would be named as 1, 2, and 3, respectively. If part 2 was also a multipart content containing two parts, these would be named as 2.1 and 2.2, respectively. Note that the -part switch is effective for only messages containing a multipart content. If a message has some other kind of content, or if the part is itself another multipart content, the -part switch will not prevent the content from being acted upon.

A content specification consists of a content type and a subtype. The initial list of `standard' content types and subtypes can be found in RFC-2046.

A list of commonly used contents is briefly reproduced here:

    Type	Subtypes
    ----	--------
    text	plain, enriched
    multipart	mixed, alternative, digest, parallel
    message	rfc822, partial, external-body
    application	octet-stream, postscript
    image	jpeg, gif, png
    audio	basic
    video	mpeg

A legal MIME message must contain a subtype specification.

To specify a content, regardless of its subtype, just use the name of the content, e.g., `audio'. To specify a specific subtype, separate the two with a slash, e.g., `audio/basic'. Note that regardless of the values given to the -type switch, a multipart content (of any subtype listed above) is always acted upon.
