tracker-extract - Extract metadata from a file.
tracker-extract [OPTION...] FILE...
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.
Show summary of options.
Set verbosity to N. This overrides the config value. Values include 0=errors,
1=minimal, 2=detailed and 3=debug.
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.
The MIME type to use for the file. If one is not provided, it will be guessed auto-
Disable shutting down after 30 seconds of inactivity.
Use this option to force internal extractors over 3rd parties like libstreamana-
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
Show binary version.
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
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-
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/.
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
tracker-store(1), tracker-sparql(1), tracker-stats(1), tracker-info(1).
