tracker-extract
tracker-extract(1) User Commands tracker-extract(1)
NAME
tracker-extract - Extract metadata from a file.
SYNOPSYS
tracker-extract [OPTION...] FILE...
DESCRIPTION
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.
OPTIONS
-?, --help
Show summary of options.
-v, --verbosity=N
Set verbosity to N. This overrides the config value. Values include 0=errors, 1=minimal, 2=detailed and 3=debug.
-f, --file=FILE
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.
-m, --mime=MIME
The MIME type to use for the file. If one is not provided, it will be guessed automatically.
-d, --disable-shutdown
Disable shutting down after 30 seconds of inactivity.
-i, --force-internal-extractors
Use this option to force internal extractors over 3rd parties like libstreamanalyzer.
-m, --force-module=MODULE
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-
tation.
-V, --version
Show binary version.
EXAMPLES
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
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.
FILES
$HOME/.config/tracker/tracker-extract.cfg
