mhlist - list information about MIME messages
mhlist [+folder] [msgs] [-file file] [-part number] ... [-type content] ... [-headers | -noheaders] [-realsize | -norealsize] [-rcache policy] [-wcache policy] [-check | -nocheck] [-version] [-help]
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)). The -headers switch indicates that a one-line banner should be displayed above the listing. The -realsize switch tells mhlist to evaluate the “native” (decoded) format of each content prior to listing. 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 nmh message. It should NOT be in mail drop format (to convert a file in mail drop format to a folder of nmh 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. Further note that if the -type switch is used, and it is desirable to act on a message/external-body content, then the -type switch must be used twice: once for message/external-body and once for the content externally referenced. Checking the Contents The -check switch tells mhlist to check each content for an integrity checksum. If a content has such a checksum (specified as a Content-MD5 header field), then mhlist will attempt to verify the integrity of the content.
