tracker-info - Retrieve all information available for a certain file.


tracker info [options...] <file1> [[file2] ...]


tracker info asks for all the known metadata available for the given file.
Multiple file arguments can be provided to retrieve information about multiple files.
The file argument can be either a local path or a URI. It also does not have to be an absolute path.


-f, --full-namespaces
By default, all keys and values reported about any given file are returned in shortened form, for example, nie:title is shown instead of This makes things much easier to see generally and the output is less cluttered. This option reverses that so FULL namespaces are shown instead.
-c, --plain-text-content
If the resource being displayed has nie:PlainTextContent (i.e. information about the content of the resource, which could be the contents of a file on the disk), then this option displays that in the output.
-i, --resource-is-iri
In most cases, the file argument supplied points to a URL or PATH which is queried for according to the resource associated with it by nie:url. However, in cases where the file specified turns out to be the actual URN itself, this argument is required to tell "tracker info" not to do the extra step of looking up the URN related by nie:url.
For example, consider that you store URNs by the actual URL itself and use the unique nie:url in another resource (which is quite reasonable when using containers and multi-resource conditions), you would need this argument to tell "tracker info" that the file supplied is actually a URN not URL.
-t, --turtle
Output results as Turtle RDF. If -f is enabled, full URIs are shown for subjects, predicates and objects; otherwise, shortened URIs are used, and all the prefixes Tracker knows about are printed at the top of the output.


This option allows you to choose which backend you use for connecting to the database. This choice can limit your functionality. There are three settings.
With " direct" the connection to the database is made directly to the file itself on the disk, there is no intermediary daemon or process. The " direct" approach is purely read-only.
With " bus" the tracker-store process is used to liase with the database queuing all requests and managing the connections via an IPC / D-Bus. This adds a small overhead BUT this is the only approach you can use if you want to write to the database.
With " auto" the backend is decided for you, much like it would be if this environment variable was undefined.
