NAME¶
mu_extract - display and save message parts (attachments), and open them with
other tools.
SYNOPSIS¶
mu extract [options] <file> mu extract [options] <file>
<pattern>
DESCRIPTION¶
mu extact is the
mu sub-command for extracting MIME-parts (e.g.,
attachments) from mail messages. It works on message files, and does not
require the message to be indexed in the database.
For attachments, the file name used when saving it, is the name of the
attachment in the message. If there is no such name, or when saving
non-attachment MIME-parts, a name is derived from the message-id of the
message.
If you specify a pattern (a case-insensitive regular expression) as the second
argument, all attachments with filenames matching that pattern will be
extracted. The regular expressions are Perl-compatible (as per the
PCRE-library).
Without any options,
mu extract simply outputs the list of leaf
MIME-parts in the message. Only 'leaf' MIME-parts (including RFC822
attachments) are considered,
multipart/* etc. are ignored.
OPTIONS¶
- -a, --save-attachments
- save all MIME-parts that look like attachments.
- --save-all
- save all non-multipart MIME-parts.
- --parts=<parts>
- only consider the following numbered parts (comma-separated
list).The numbers for the parts can be seen from running mu extract
without any options but only the message file.
- --target-dir=<dir>
- save the parts in the target directory rather than the
current working directory.
- --overwrite
- overwrite existing files with the same name; by default
overwriting is not allowed.
- --play Try to 'play' (open) the attachment with the
default
- application for the particular file type. On MacOS, this
uses the open program, on other platforms is uses xdg-open.
You can choose a different program by setting the MU_PLAY_PROGRAM
environment variable.
EXAMPLES¶
To display information about all the MIME-parts in a message file:
$ mu extract msgfile
To extract MIME-part 3 and 4 from this message, overwriting existing files with
the same name:
$ mu extract --parts=3,4 --overwrite msgfile
To extract all files ending in '.jpg' (case-insensitive):
$ mu extract msgfile '.*.jpg'
To extract an mp3-file, and play it in the the default mp3-playing application.
$ mu extract --play msgfile 'whoopsididitagain.mp3'
