# tracker-stats(1)

Provides statistics on the data indexed

## NAME

tracker-stats - Provides statistics on the data indexed

## SYNOPSIS

**tracker-stats** \[*OPTION*...\] \[\[*EXPRESSION*...\] \[*EXPRESSION*...\]\]

## DESCRIPTION

Display statistics about RDF classes in and how many of each exist for the data set that has been indexed.

By default, only common and useful classes are shown, e.g. nfo:Document or nfo:Folder, for a full set of statistics, see the option.

If one or more *EXPRESSION* is given, the statistics returned are filtered to only include information about RDF types matching *EXPRESSION* (case folded and matching accented variants).

The RDF classes are detailed by the **Nepomuk** ontology specification. These classes can be used to further query more information using **SparQL** with **tracker-sparql.**

## OPTIONS

- **-h, --help**

  Show a brief help message.

- **-a, --all**

  Display statistics about ALL RDF classes that exist in the database. Without this option only the common RDF classes will be shown, for example nfo:Document and nfo:FileDataObject.

  This option is implied if search terms are provided to filter ALL possible statistics.

- **-V, --version**

  Print version.
