NAME

       reformime - MIME E-mail reformatting tool

SYNOPSIS

       reformime [options...]

DESCRIPTION

       reformime is a utility for reformatting MIME messages.

       Generally, reformime expects to see an RFC 2045[1] compliant message on standard input,
       except in few cases such as the -m option.

       If no options are given, reformime prints the MIME structure of the message. The output
       consists of so-called "MIME reference tags", one per line. For example:

           1
           1.1
           1.2

       This shows that the message contains two different MIME sections. The first line of the
       MIME structure output will always contain "1", which refers to the entire message. In this
       case it happens to be a multipart/mixed message. "1.1" refers to the first section of the
       multipart message, which happens to be a text/plain section. "1.2" refers to the second
       section of the message, which happens to be an application/octet-stream section.

       If the message is not a MIME message, or it does not contain any attachments, reformime
       prints only "1", that refers to the entire message itself:

           1

       Here's the output from reformime when the first part of the message was itself a
       multipart/alternative section:

           1
           1.1
           1.1.1
           1.1.2
           1.2

       Arbitrarily complex MIME constructs are possible.

OPTIONS

       -d
           Parse a delivery status notification MIME message (RFC 1894[2]).  reformime expects to
           see on standard input a MIME message that consists of a delivery status notification,
           as defined by RFC 1894.  reformime reads the message and prints on standard output a
           list of addresses and their corresponding delivery status, as specified in the
           delivery status notification. Each line printed by reformime consists of a delivery
           status, a space, and the address.  reformime then terminates with a 0 exit status.
           reformime produces no output and terminates with an exit status of 1 if the standard
           input does not contain a delivery status notification.

       -D
           Like the -d except that reformime lists the address found in the Original-Recipient:
           header, if it exists.

       -e
           Extract the contents of the indicated MIME section, and display it on standard output.
           The -s option is required when -e is specified. If the specified section or sections
           use either the base64 or quoted-printable encoding method, reformime automatically
           decodes it. In this case you're better off redirecting the standard output into a
           file.

       -i
           Display MIME information for each section.  reformime displays the contents of the
           Content-Type: header, any encoding used, and the character set.  reformime also
           displays the byte offset in the message where each section starts and ends (and where
           the actual contents of the section start, after skipping all the headers).

       -m
           Create a multipart/digest MIME message digest.

       -r
           Rewrite message, adding or standardizing RFC 2045[1] MIME headers.

       -r7
           Like -r but also convert 8bit-encoded MIME sections to quoted-printable.

       -r8
           Like -r but also convert quoted-printable-encoded MIME sections to 8bit.

       -s section
           Display MIME information for this section only.  section is a MIME specification tag.
           The -s option is required if -e is also specified, and is optional with -i.

           Multiple sections may be specified by separating them with commas.  reformime
           processes each section using the other options that were specified.

       -x
           Extract the contents of the indicated MIME section to a file.

       -X
           Pipe the contents of the indicated MIME section to a program.

   Extracting RFC 2045 MIME section(s) to file(s)
       The -x and -X options extract a specific MIME section to a file or to a pipe to an
       external program. Use the -s option to identify the MIME section to extract. If the -s
       option is not specified, every MIME section in the message is extracted, one at a time. If
       -s lists multiple sections, each section gets extracted separately.  quoted-printable and
       base64 encoding are automatically decoded.

       -x
           Interactive extraction.  reformime prints the MIME content type of each section.
           Answer with 'y' or 'Y' to extract the MIME section. Specify the filename at the next
           prompt.  reformime prompts with a default filename.  reformime tries to choose the
           default filename based on the MIME headers, if possible. If not, the default filename
           will be attachment1.dat (if the -s option is not specified, the next filename will be
           attachment2.dat, and so on).

       -xPREFIX
           Automatic extraction.  reformime automatically extracts one or more MIME sections, and
           saves them to a file. The filename is formed by taking PREFIX, and appending the
           default filename to it. Note that there's no space between "-x" and "PREFIX". For
           example:

               reformime -xfiles-
           This command saves MIME sections as files-attachment1.dat, then files-attachment2.dat,
           etc.  reformime tries to append the filename specified in the MIME headers for each
           section, where possible.  reformime replaces all suspect characters with the
           underscore character.

       -X prog arg1 arg2 ...
           The -X option must be the last option to reformime.  reformime runs an external
           program prog, and pipes the contents of the MIME section to the program.  reformime
           sets the environment variable CONTENT_TYPE to the MIME content type. The environment
           variable FILENAME gets set to the default filename of reformime's liking. If the -s
           option is not specified, the program runs once for every MIME section in the message.
           The external program, prog must terminate with a zero exit status in order for
           reformime to proceed to the next MIME section in the message (or the next section
           specified by -s). In any case, if prog terminates with a non-zero exit status,
           reformime terminates with the exit status of 20 plus prog's exit status.

           Note
           reformime extracts every MIME section in the message unless the -s option is
           specified. This includes even the text/plain MIME content that usually precedes a
           binary attachment.

   Adding RFC 2045 MIME headers
       The -r option performs the following actions:

       If there is no Mime-Version:, Content-Type:, or Content-Transfer-Encoding: header,
       reformime adds one.

       If the Content-Transfer-Encoding: header contains 8bit or raw, but only seven-bit data is
       found, reformime changes the Content-Transfer-Encoding header to 7bit.

       -r7 does the same thing, but also converts 8bit-encoded content that contains eight-bit
       characters to quoted-printable encoding.

       -r8 does the same thing, but also converts quoted-printable-encoded content to 8bit,
       except in some situations.

   Creating multipart/digest MIME digests
       The -m option creates a MIME digest.  reformime reads a list of filenames on standard
       input. Each line read from standard input contains the name of a file that is presumed to
       contain an RFC 2822-formatted message.  reformime splices all files into a
       multipart/digest MIME section, and writes it to standard output.

   Translating MIME headers
       The following options do not read a message from standard input. These options process
       MIME headers via the command line, and are designed to be conveniently used by
       mail-handling scripts.

       -h "header"
           Decode a MIME-encoded "header" and print the decoded 8-bit content on standard output.
           The decoding gets carried out as if the contents occurred in the “Subject” header.
           Example:

               $ reformime -h '=?iso-8859-1?Q?H=F3la!?='
               Hóla!

       -H "header"
           Like -h except that header is parsed as a list of email addresses, like “From” or
           “To”.

       -o "text"
           MIME-encode "text", and print the results on standard output.

       -O "text"
           Like the -o option, except that text is a structured header with RFC 2822 addresses.

       -c "charset"
           Use charset as the character set setting, by the -h, -H, -o and -O options.

       -u
           This “undocumented” option reads a MIME message on standard input, and converts its
           contents to an UTF-8-encoded character stream, which is written to standard output.

           The standard output receives a concatenated amalgam of the headers and “text” MIME
           object data. It is meant to be used as part of a generic search function. This option
           decodes various kinds of header MIME encoding, the quoted-printable and base64
           transfer encodings of “text” MIME objects.
