MU-EXTRACT(1)                                                 General Commands Manual                                                MU-EXTRACT(1)

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 pat-
       tern 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 attach-
       ments) 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'
