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'
