REFORMIME(1)REFORMIME(1)NAMEreformime - MIME E-mail reformatting tool
SYNOPSISreformime [ options ... ]
DESCRIPTIONreformime is a utility for reformatting MIME messages.
Generally, reformime expects to see an RFC 2045 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 multi‐
part/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 applica‐
tion/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 mes‐
sage 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).
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 Rxtract the contents of the indicated MIME section, and display
it on standard output. The -s option is required when -e is
specified. If the indicated section uses either the base64 or
quoted-printable encoding method, reformime automatically
decodes it. In this case you're better off redirecting the stan‐
dard 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 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.
-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 sec‐
tion in the message is extracted, one at a time. 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 pro‐
gram 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. 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 attach‐
ment.
ADDING RFC 2045 MIME HEADERS
The -r option performs the following actions:
If there is no Mime-Version:, Content-Type:, or Content-Transfer-Encod‐
ing: 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-Encod‐
ing 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 file‐
names 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 sec‐
tion, 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 con‐
tent on standard output. Example:
$ reformime-h '=?iso-8859-1?Q?H=F3la!?='
H�la!
-o "text"
MIME-encode "text", and print the results on standard output.
Use the -c option to specify the character set.
-O "text"
Like the -o option, except that text is a structured header with
RFC 2822 addresses.
