tracker-extract(1) User Commands tracker-extract(1)

tracker-extract - Extract metadata from a file.

tracker extract FILE

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.

-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.

Using command line to extract metadata from a file:

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

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/

tracker-store(1), tracker-sparql(1), tracker-stats(1), tracker-info(1).
