10
12 reformime is a utility for reformatting MIME messages.
13 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 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 1
22 1.1
23 1.2
24 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 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 Here´s the output from reformime when the first part of the message was
38 itself a multipart/alternative section:
39 1
41 1.1
42 1.1.1
43 1.1.2
44 1.2
45 Arbitrarily complex MIME constructs are possible.
47
49 -d
50 Parse a delivery status notification MIME message (RFC 1894[2]).
51 reformime expects to see on standard input a MIME message that
52 consists of a delivery status notification, as defined by RFC 1894.
53 reformime reads the message and prints on standard output a list of
54 addresses and their corresponding delivery status, as specified in
55 the delivery status notification. Each line printed by reformime
56 consists of a delivery status, a space, and the address. reformime
57 then terminates with a 0 exit status. reformime produces no output
58 and terminates with an exit status of 1 if the standard input does
59 not contain a delivery status notification.
60 -D
62 Like the -d except that reformime lists the address found in the
63 Original-Recipient: header, if it exists.
64 -e
66 Extract the contents of the indicated MIME section, and display it
67 on standard output. The -s option is required when -e is specified.
68 If the indicated section uses either the base64 or quoted-printable
69 encoding method, reformime automatically decodes it. In this case
70 you´re better off redirecting the standard output into a file.
71 -i
73 Display MIME information for each section. reformime displays the
74 contents of the Content-Type: header, any encoding used, and the
75 character set. reformime also displays the byte offset in the
76 message where each section starts and ends (and where the actual
77 contents of the section start, after skipping all the headers).
78 -m
80 Create a multipart/digest MIME message digest.
81 -r
83 Rewrite message, adding or standardizing RFC 2045[1] MIME headers.
84 -r7
86 Like -r but also convert 8bit-encoded MIME sections to
87 quoted-printable.
88 -r8
90 Like -r but also convert quoted-printable-encoded MIME sections to
91 8bit.
92 -s section
94 Display MIME information for this section only. section is a MIME
95 specification tag. The -s option is required if -e is also
96 specified, and is optional with -i.
97 -x
99 Extract the contents of the indicated MIME section to a file.
100 -X
102 Pipe the contents of the indicated MIME section to a program.
103 Extracting RFC 2045 MIME section(s) to file(s)
105 The -x and -X options extract a specific MIME section to a file or to a
106 pipe to an external program. Use the -s option to identify the MIME
107 section to extract. If the -s option is not specified, every MIME
108 section in the message is extracted, one at a time. quoted-printable
109 and base64 encoding are automatically decoded.
110 -x
112 Interactive extraction. reformime prints the MIME content type of
113 each section. Answer with ´y´ or ´Y´ to extract the MIME section.
114 Specify the filename at the next prompt. reformime prompts with a
115 default filename. reformime tries to choose the default filename
116 based on the MIME headers, if possible. If not, the default
117 filename will be attachment1.dat (if the -s option is not
118 specified, the next filename will be attachment2.dat, and so on).
119 -xPREFIX
121 Automatic extraction. reformime automatically extracts one or more
122 MIME sections, and saves them to a file. The filename is formed by
123 taking PREFIX, and appending the default filename to it. Note that
124 there´s no space between "-x" and "PREFIX". For example:
125 reformime -xfiles-
127 This command saves MIME sections as files-attachment1.dat, then
128 files-attachment2.dat, etc. reformime tries to append the filename
129 specified in the MIME headers for each section, where possible.
130 reformime replaces all suspect characters with the underscore
131 character.
132 -X prog arg1 arg2 ...
134 The -X option must be the last option to reformime. reformime runs
135 an external program prog, and pipes the contents of the MIME
136 section to the program. reformime sets the environment variable
137 CONTENT_TYPE to the MIME content type. The environment variable
138 FILENAME gets set to the default filename of reformime´s liking. If
139 the -s option is not specified, the program runs once for every
140 MIME section in the message. The external program, prog must
141 terminate with a zero exit status in order for reformime to proceed
142 to the next MIME section in the message. In any case, if prog
143 terminates with a non-zero exit status, reformime terminates with
144 the exit status of 20 plus prog´s exit status.
145 Note
147 reformime extracts every MIME section in the message unless the -s
148 option is specified. This includes even the text/plain MIME content
149 that usually precedes a binary attachment.
150 Adding RFC 2045 MIME headers
152 The -r option performs the following actions:
153 If there is no Mime-Version:, Content-Type:, or
155 Content-Transfer-Encoding: header, reformime adds one.
156 If the Content-Transfer-Encoding: header contains 8bit or raw, but only
158 seven-bit data is found, reformime changes the
159 Content-Transfer-Encoding header to 7bit.
160 -r7 does the same thing, but also converts 8bit-encoded content that
162 contains eight-bit characters to quoted-printable encoding.
163 -r8 does the same thing, but also converts quoted-printable-encoded
165 content to 8bit, except in some situations.
166 Creating multipart/digest MIME digests
168 The -m option creates a MIME digest. reformime reads a list of
169 filenames on standard input. Each line read from standard input
170 contains the name of a file that is presumed to contain an RFC
171 2822-formatted message. reformime splices all files into a
172 multipart/digest MIME section, and writes it to standard output.
173 Translating MIME headers
175 The following options do not read a message from standard input. These
176 options process MIME headers via the command line, and are designed to
177 be conveniently used by mail-handling scripts.
178 -h "header"
180 Decode a MIME-encoded "header" and print the decoded 8-bit content
181 on standard output. The decoding gets carried out as if the
182 contents occurred in the “Subject” header. Example:
183 $ reformime -h ´=?iso-8859-1?Q?H=F3la!?=´
185 Hóla!
186 -H "header"
188 Like -h except that header is parsed as a list of email addresses,
189 like “From” or “To”.
190 -o "text"
192 MIME-encode "text", and print the results on standard output.
193 -O "text"
195 Like the -o option, except that text is a structured header with
196 RFC 2822 addresses.
197 -c "charset"
199 Use charset as the character set setting, by the -h, -H, -o and -O
200 options.
