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
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
The MIME type to use for the file. If one is not provided, it will be guessed automatically.
Disable shutting down after 30 seconds of inactivity.
Use this option to force internal extractors over 3rd parties like libstreamanalyzer.
Force a particular module to be used. This is here as a convenience for developers wanting to test their MODULE file. Only the MOD-
ULE 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 con-
tain the correct symbols to be authenticated by tracker-extract. For more information see the libtracker-extract reference documen-
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 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-0.10/extract-modules/.
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/.
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).
