SYNOPSIS

9       reformime [options...]
10

DESCRIPTION

12       reformime is a utility for reformatting MIME messages.
13
14       Generally, reformime expects to see an RFC 2045[1] compliant message on
15       standard input, except in few cases such as the -m option.
16
17       If no options are given, reformime prints the MIME structure of the
18       message. The output consists of so-called "MIME reference tags", one
19       per line. For example:
20
21           1
22           1.1
23           1.2
24
25       This shows that the message contains two different MIME sections. The
26       first line of the MIME structure output will always contain "1", which
27       refers to the entire message. In this case it happens to be a
28       multipart/mixed message. "1.1" refers to the first section of the
29       multipart message, which happens to be a text/plain section. "1.2"
30       refers to the second section of the message, which happens to be an
31       application/octet-stream section.
32
33       If the message is not a MIME message, or it does not contain any
34       attachments, reformime prints only "1", that refers to the entire
35       message itself:
36
37           1
38
39       Here's the output from reformime when the first part of the message was
40       itself a multipart/alternative section:
41
42           1
43           1.1
44           1.1.1
45           1.1.2
46           1.2
47
48       Arbitrarily complex MIME constructs are possible.

OPTIONS

51       -d
52           Parse a delivery status notification MIME message (RFC 1894[2]).
53           reformime expects to see on standard input a MIME message that
54           consists of a delivery status notification, as defined by RFC 1894.
55           reformime reads the message and prints on standard output a list of
56           addresses and their corresponding delivery status, as specified in
57           the delivery status notification. Each line printed by reformime
58           consists of a delivery status, a space, and the address.  reformime
59           then terminates with a 0 exit status.  reformime produces no output
60           and terminates with an exit status of 1 if the standard input does
61           not contain a delivery status notification.
62
63       -D
64           Like the -d except that reformime lists the address found in the
65           Original-Recipient: header, if it exists.
66
67       -e
68           Extract the contents of the indicated MIME section, and display it
69           on standard output. The -s option is required when -e is specified.
70           If the specified section or sections use either the base64 or
71           quoted-printable encoding method, reformime automatically decodes
72           it. In this case you're better off redirecting the standard output
73           into a file.
74
75       -i
76           Display MIME information for each section.  reformime displays the
77           contents of the Content-Type: header, any encoding used, and the
78           character set.  reformime also displays the byte offset in the
79           message where each section starts and ends (and where the actual
80           contents of the section start, after skipping all the headers).
81
82       -m
83           Create a multipart/digest MIME message digest.
84
85       -r
86           Rewrite message, adding or standardizing RFC 2045[1] MIME headers.
87
88       -r7
89           Like -r but also convert 8bit-encoded MIME sections to
90           quoted-printable.
91
92       -r8
93           Like -r but also convert quoted-printable-encoded MIME sections to
94           8bit.
95
96       -s section
97           Display MIME information for this section only.  section is a MIME
98           specification tag. The -s option is required if -e is also
99           specified, and is optional with -i.
100
101           Multiple sections may be specified by separating them with commas.
102           reformime processes each section using the other options that were
103           specified.
104
105       -x
106           Extract the contents of the indicated MIME section to a file.
107
108       -X
109           Pipe the contents of the indicated MIME section to a program.
110
111   Extracting RFC 2045 MIME section(s) to file(s)
112       The -x and -X options extract a specific MIME section to a file or to a
113       pipe to an external program. Use the -s option to identify the MIME
114       section to extract. If the -s option is not specified, every MIME
115       section in the message is extracted, one at a time. If -s lists
116       multiple sections, each section gets extracted separately.
117       quoted-printable and base64 encoding are automatically decoded.
118
119       -x
120           Interactive extraction.  reformime prints the MIME content type of
121           each section. Answer with 'y' or 'Y' to extract the MIME section.
122           Specify the filename at the next prompt.  reformime prompts with a
123           default filename.  reformime tries to choose the default filename
124           based on the MIME headers, if possible. If not, the default
125           filename will be attachment1.dat (if the -s option is not
126           specified, the next filename will be attachment2.dat, and so on).
127
128       -xPREFIX
129           Automatic extraction.  reformime automatically extracts one or more
130           MIME sections, and saves them to a file. The filename is formed by
131           taking PREFIX, and appending the default filename to it. Note that
132           there's no space between "-x" and "PREFIX". For example:
133
134               reformime -xfiles-
135           This command saves MIME sections as files-attachment1.dat, then
136           files-attachment2.dat, etc.  reformime tries to append the filename
137           specified in the MIME headers for each section, where possible.
138           reformime replaces all suspect characters with the underscore
139           character.
140
141       -X prog arg1 arg2 ...
142           The -X option must be the last option to reformime.  reformime runs
143           an external program prog, and pipes the contents of the MIME
144           section to the program.  reformime sets the environment variable
145           CONTENT_TYPE to the MIME content type. The environment variable
146           FILENAME gets set to the default filename of reformime's liking. If
147           the -s option is not specified, the program runs once for every
148           MIME section in the message. The external program, prog must
149           terminate with a zero exit status in order for reformime to proceed
150           to the next MIME section in the message (or the next section
151           specified by -s). In any case, if prog terminates with a non-zero
152           exit status, reformime terminates with the exit status of 20 plus
153           prog's exit status.
154
155           Note
156           reformime extracts every MIME section in the message unless the -s
157           option is specified. This includes even the text/plain MIME content
158           that usually precedes a binary attachment.
159
160   Adding RFC 2045 MIME headers
161       The -r option performs the following actions:
162
163       If there is no Mime-Version:, Content-Type:, or
164       Content-Transfer-Encoding: header, reformime adds one.
165
166       If the Content-Transfer-Encoding: header contains 8bit or raw, but only
167       seven-bit data is found, reformime changes the
168       Content-Transfer-Encoding header to 7bit.
169
170       -r7 does the same thing, but also converts 8bit-encoded content that
171       contains eight-bit characters to quoted-printable encoding.
172
173       -r8 does the same thing, but also converts quoted-printable-encoded
174       content to 8bit, except in some situations.
175
176   Creating multipart/digest MIME digests
177       The -m option creates a MIME digest.  reformime reads a list of
178       filenames on standard input. Each line read from standard input
179       contains the name of a file that is presumed to contain an RFC
180       2822-formatted message.  reformime splices all files into a
181       multipart/digest MIME section, and writes it to standard output.
182
183   Translating MIME headers
184       The following options do not read a message from standard input. These
185       options process MIME headers via the command line, and are designed to
186       be conveniently used by mail-handling scripts.
187
188       -h "header"
189           Decode a MIME-encoded "header" and print the decoded 8-bit content
190           on standard output. The decoding gets carried out as if the
191           contents occurred in the “Subject” header. Example:
192
193               $ reformime -h '=?iso-8859-1?Q?H=F3la!?='
194               Hóla!
195
196       -H "header"
197           Like -h except that header is parsed as a list of email addresses,
198           like “From” or “To”.
199
200       -o "text"
201           MIME-encode "text", and print the results on standard output.
202
203       -O "text"
204           Like the -o option, except that text is a structured header with
205           RFC 2822 addresses.
206
207       -c "charset"
208           Use charset as the character set setting, by the -h, -H, -o and -O
209           options.
210
211       -u
212           This “undocumented” option reads a MIME message on standard input,
213           and converts its contents to an UTF-8-encoded character stream,
214           which is written to standard output.
215
216           The standard output receives a concatenated amalgam of the headers
217           and “text” MIME object data. It is meant to be used as part of a
218           generic search function. This option decodes various kinds of
219           header MIME encoding, the quoted-printable and base64 transfer
220           encodings of “text” MIME objects.
