NAME
       tracker-extract - Extract metadata from a file.

SYNOPSYS
       tracker-extract [OPTION...] FILE...

DESCRIPTION
       tracker-extract	reads  the  file  and mimetype provided in stdin and extract the metadata
       from this file; then it displays the metadata on the standard output.

       NOTE: If a FILE is not provided then tracker-extract will run for 30 seconds  waiting  for
       DBus calls before quitting.

OPTIONS
       -?, --help
	      Show summary of options.

       -v, --verbosity=N
	      Set  verbosity  to  N.  This  overrides the config value.  Values include 0=errors,
	      1=minimal, 2=detailed and 3=debug.

       -f, --file=FILE
	      The FILE to extract metadata from. The FILE argument can be either a local path  or
	      a URI. It also does not have to be an absolute path.

       -m, --mime=MIME
	      The MIME type to use for the file. If one is not provided, it will be guessed auto-
	      matically.

       -d, --disable-shutdown
	      Disable shutting down after 30 seconds of inactivity.

       -i, --force-internal-extractors
	      Use this option to force internal extractors over 3rd  parties  like  libstreamana-
	      lyzer.

       -m, --force-module=MODULE
	      Force  a particular module to be used. This is here as a convenience for developers
	      wanting to test their MODULE file. Only the MODULE name has to  be  specified,  not
	      the  full  path.	Typically, a MODULE is installed to /usr/lib/tracker-0.7/extract-
	      modules/.  This option can be used with or without the .so part of  the  name  too,
	      for example, you can use --force-module=foo

	      Modules  are  shared  objects which are dynamically loaded at run time. These files
	      must have the .so suffix to be loaded and must contain the correct  symbols  to  be
	      authenticated  by tracker-extract.  For more information see the libtracker-extract
	      reference documentation.

       -V, --version
	      Show binary version.

EXAMPLES
       Using command line to extract metadata from a file:

	       $ tracker-extract -v 3 -f /path/to/some/file.mp3

       Using a specific module to extract metadata from a file:

	       $ tracker-extract -v 3 -f /path/to/some/file.mp3 -m mymodule

ENVIRONMENT
       TRACKER_EXTRACTORS_DIR
	      This is the directory which tracker uses to load the shared  libraries  from  (used
	      for  extracting metadata for specific file types). These are needed on each invoca-
	      tion of tracker-store. If unset it will default to the correct place. This is  used
	      mainly for testing purposes. The default location is /usr/lib/tracker-0.10/extract-
	      modules/.

       TRACKER_EXTRACTOR_RULES_DIR
	      This is the directory which tracker uses to load the rules files from.   The  rules
	      files  describe extractor modules and their supported MIME types. The default loca-
	      tion is /usr/share/tracker/extract-rules/.

       TRACKER_USE_CONFIG_FILES
	      Don't use GSettings, instead use a config file similar to how settings  were  saved
	      in  0.10.x.  That  is,  a file which is much like an .ini file.  These are saved to
	      $HOME/.config/tracker/
