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 extract is the
mu sub-command for extracting MIME-parts (e.g.,
attachments) from mail messages. The sub-command 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 it 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 default mp3-playing application:
$ mu extract --play msgfile 'whoopsididitagain.mp3'
