NAME

       muextract - display and save message parts (attachments), and open them with other tools.

SYNOPSIS

       mu [common-options] extract [options] <file>

       mu [common-options] 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 regular express pattern as the second argument, all attachments with filenames matching
       that pattern will be extracted. The regular  expressions  are  basic  PCRE,  and  are  case-sensitive  by
       default; see pcre(3) for more details.

       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.

EXTRACT 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.

   -u,--uncooked
       by  default,  mu  transforms the attachment filenames a bit (such as by replacing spaces by dashes); with
       this option, leave that to the minimum for creating a legal filename in the target directory.

   --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 MUPLAYPROGRAM environment variable.

COMMON OPTIONS

   -d, --debug
       makes mu generate extra debug information, useful for debugging the program  itself.  By  default,  debug
       information  goes  to the log file, ~/.cache/mu/mu.log.  It can safely be deleted when mu is not running.
       When running with --debug option, the log file can grow rather quickly. See the note on logging below.

   -q, --quiet
       causes mu not to output informational messages and progress information to standard output, but  only  to
       the log file. Error messages will still be sent to standard error. Note that mu index is much faster with
       --quiet, so it is recommended you use this option when using mu from scripts etc.

   --log-stderr
       causes mu to not output log messages to standard error, in addition to sending them to the log file.

   --nocolor
       do not use ANSI colors. The environment variable NOCOLOR can be used as an alternative to --nocolor.

   -V, --version
       prints mu version and copyright information.

   -h, --help
       lists the various command line options.

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'
