NAME
       tracker-extract - Extract metadata from a file.

SYNOPSYS
       tracker extract FILE

DESCRIPTION
       tracker	extract	 reads	the file provided and extracts any metadata it
       can from	this file, then	displays the metadata on standard output.

       The metadata is displayed as a SPARQL update command, that can  be  run
       against a SPARQL	endpoint to update its copy of the metadata.

       The  actual  extraction	is done	by a separate process. This is done to
       isolate the calling process from	any memory leaks or crashes in the li-
       braries Tracker uses to extract metadata.

       For  more  information  see the libtracker-extract reference documenta-
       tion.

OPTIONS
       -v, --verbosity=<LEVEL>
	      This sets	the log	verbosity for the extractor process.

	      The possible LEVEL options are:

	       o   debug - Show	EVERYTHING, from debug messages	to errors.

	       o   detailed - Show enough detail to understand what is happen-
		   ing.

	       o   minimal - Show an overview of what is going on

	       o   errors  -  Show  only  warnings, criticals, errors or fatal
		   events.

       -o, --output-format=<FORMAT>
	      Choose which format to use to output results. Supported  formats
	      are sparql and turtle.

EXAMPLES
       Using command line to extract metadata from a file:

	       $ tracker extract /path/to/some/file.mp3

ENVIRONMENT
       TRACKER_EXTRACTORS_DIR
	      This  is the directory which tracker uses	to load	the shared li-
	      braries from (used for extracting	 metadata  for	specific  file
	      types). These are	needed on each invocation 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-1.0/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 sup-
	      ported	MIME	types.	   The	   default     location	    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/
