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 libraries Tracker uses to extract metadata.

       For more information see the libtracker-extract reference documentation.


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

              The possible LEVEL options are:

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

               •   detailed - Show enough detail to understand what is happening.

               •   minimal - Show an overview of what is going on

               •   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, turtle and json-ld.


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 libraries 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   supported   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/
